SUBSTITUTE OPINION
Our opinion dated November 23, 2010 is hereby withdrawn, and we issue this substitute opinion.
In this appeal, we examine whether a recent decision from the U.S. Supreme Court enlarges the duty of the trial court to ensure that all mitigating evidence is fully developed during sentencing. Finding no support for the proposition under the cited authority, we overrule appellant’s sole issue and affirm the judgment below.
BACKGROUND
On the night of July 7, 2008, appellant Nathaniel Dwayne Welch and two other men robbed a Whataburger in southeast Houston. Appellant secured the dining area of the restaurant while the other two forced the manager to open the safe. Wielding a shotgun at point-blank range, appellant threatened to kill several patrons if they did not hand over their wallets. In one instance, appellant even used the butt of his weapon to strike a patron. The robbers left without any shots being fired, but police pursued the getaway vehicle, eventually apprehending all of the suspects when their car flipped into a bayou. Appellant confessed to the crime and pleaded guilty to a charge of aggravated robbery. At the time of the offense, he was seventeen years old.
Appellant elected to have punishment assessed by the trial judge. During the sentencing hearing, appellant objected to statements in the presentence investigation report indicating that he was “in good physical health” and “never ... sought or *378 received psychiatric or psychological evaluation or counseling.” Appellant claimed that his medical records revealed a “serious head trauma at age three” and a long psychiatric history of delusions, hallucinations, psychosis, depression, and bipolar disorder. 1 Appellant did not specifically request that the trial court order further psychological evaluations.
In his presentation of mitigating evidence, appellant testified that he fell down a flight of stairs when he was a child. To this day, appellant has a metal plate in his head because of the injuries sustained. Appellant also testified as to his troubled childhood. He said that he often transferred between schools and struggled with reading. He said that his father was largely absent. For a period of time, he lived on his own with just his half-brother, when both were beneath the age of fourteen. Finally, appellant testified that his mother killed a beloved aunt in a car accident, causing the family to “fall apart.”
At the close of the hearing, the trial judge made the following comment:
It is a bad aggravated robbery. I’m going to take into account your information I heard on this date.... I’m not sure of the State’s position on the metal plate. I believe there is a metal plate, stuffs in the record and I don’t know what problems mental health caused but aside from that, there are [a] lot of people in this world — most people with mental health problems who do not go in places with shotguns and the fact of the matter is there are aggravated robbers who stand there far away from people not telling them they’re going to kill them. It’s hard to measure different aggravated robberies and compare them to one another. I still think this is a very, very bad one. Thank God it did not go any worse than it did.
The trial judge then sentenced appellant to fifteen years’ imprisonment, out of a possible five years to life. In his only issue on appeal, appellant contends a new punishment hearing is required to further explore the mitigating effect of his mental health.
DISCUSSION
Appellant relies principally on
Graham v. Florida,
— U.S. -,
I. Proportionality Review Before Graham
The Eighth Amendment prohibits the' imposition of cruel and unusual punishments. U.S. Const. amend. VIII. In addition to proscribing specific “modes” of punishment,
see, e.g., Weems v. United States,
A. Capital Cases
In the capital context, the Supreme Court has required proportionality only to the extent that the death penalty is confined “to a narrow category of the most serious crimes ... [and] only the most deserving of execution.”
Atkins v. Virginia,
In reaching these categorical determinations, the Court has examined Eighth Amendment challenges for the central question of whether the imposition of our ultimate sanction comports with “the evolving standards of decency that mark the progress of a maturing society.”
Trop v. Dulles,
Even where capital punishment is proportionate in the abstract, the Supreme Court has required additional safeguards in the method of sentencing. Because the death penalty is “unique in its total irrevo-cability,”
Furman v. Georgia,
B. Noncapital Cases
Proportionality review in the noncapital context has followed a different analytical approach. Recognizing that a term of years is different in kind from the death penalty, the Supreme Court has largely deferred to the sentencing schemes devised by the nation’s legislatures.
See Rummel v. Estelle,
Unlike challenges in the capital context, the Eighth Amendment does not similarly require individualized sentencing for a term of years.

II. The Effect of Graham
Prior to
Graham,
the two tracks of the Court’s proportionality jurisprudence remained strictly discrete. Indeed, the Court refused to apply its categorical approach in the noncapital context: “Because a sentence of death differs in kind from any sentence of imprisonment, no matter how long, our decisions applying the prohibition of cruel and unusual punishments to capital cases are of limited assistance in deciding the constitutionality of [a term of years].”
Rummel,
Appellant does not contest the ex-cessiveness or proportionality of his sentence under Graham. Rather, he argues that Graham redrew the line in regards to individualized sentencing because the Court applied the categorical approach— *381 which requires consideration of the offender’s characteristics and the circumstances of the offense — in a context where, traditionally, the Constitution has not mandated the factoring of mitigating evidence. In support of his proposition, appellant directs us to the following passage from Graham: “In accordance with the constitutional design, the task of interpreting the Eighth Amendment remains our responsibility. The judicial exercise of independent judgment requires consideration of the culpability of the offenders at issue in light of their crimes and characteristics, along with the severity of the punishment in question.” Id. at 2026 (majority opinion) (citation and internal quotation omitted).
Appellant argues that this passage establishes what he deems the “Graham safety net function.” Under this idea, reviewing courts can only exercise their independent judgment if they have an adequate record of the individual offender to consider. The argument follows, therefore, that “it becomes the trial court’s responsibility to insure [sic] that mitigating factors are adequately identified and developed for the benefit of the punishment-stage factfinder.” We disagree with appellant’s construction of Graham.
The quoted passage and its reference to the offender’s “characteristics” do not, as appellant suggests, address the need for mitigating evidence to be fully developed during sentencing. Instead, the passage clearly alludes to the second step in the Court’s categorical analysis. Before
Graham,
that step tested the appropriateness of the death penalty by ensuring either (1) the crime committed was a homicide offense, or (2) the offender was a member of the class “most deserving of execution.”
Atkins,
The procedural facts of
Graham
support our understanding of its limited implications. Because the offender in
Graham
was not punished pursuant to a mandatory sentencing scheme, he had the opportunity to produce evidence of mitigating circumstances during his sentencing hearing.
See id.
at 2018-19. Accordingly, the Court was not required to revisit the question of whether the Eighth Amendment mandates individualized consideration for a term of years sentence.
Cf. Harmelin,
III. Texas Statutory Duty
Although appellant has not argued any statutory basis for relief, we note that the Code of Criminal Procedure contains the following mechanism for ensuring that a defendant’s mental condition is adequately considered during sentencing:
A presentence- investigation conducted on any defendant convicted of a felony offense who appears to the judge *382 through its own observation or on suggestion of a party to have a mental impairment shall include a psychological evaluation which determines, at a minimum, the defendant’s IQ and adaptive behavior score. The results of the evaluation shall be included in the report to the judge as required by Subsection (a) of this section.
Tex.Code Crim. Proc. Ann. art. 42.12, § 9(i) (West 2010).
Appellant’s presentence investigation report does not indicate that a psychological evaluation was ever conducted, and appellant does not specifically complain on appeal that the trial court erred in failing to order one. Assuming
arguendo
that appellant has raised any claim involving his right to a psychological evaluation, we would still conclude that appellant is not entitled to relief under the statute. Under the presumption of regularity, we must presume that the trial court would have ordered a psychological evaluation had it observed that appellant was suffering from a mental impairment.
Cf. Wright v. State,
CONCLUSION
Appellant argues that he is entitled to a new punishment hearing because the trial court ignored its duty to ensure that mitigating evidence of his mental health was fully developed. Because we believe no such duty exists under Graham and because appellant has waived any relief under Article 42.12, we overrule appellant’s sole issue and affirm the judgment of the trial court.
Notes
. Our limited record can neither confirm nor refute appellant’s assertion that these medical records were admitted into evidence at a previous hearing on a motion for new trial.
