BACHARACH, Circuit Judge. ___________________________________________

This appeal involves a criminal sentence. In deciding on the

sentence, the district court can reduce the guideline range when the

defendant is a minor participant. U.S.S.G. § 3B1.2(b). But a defendant’s

participation can be considered minor only if most other participants bear

greater culpability. U.S.S.G. § 3B1.2 cmt. n.5. The main question in the

appeal is whether the district court plainly erred by failing to consider

more culpable participants. We answer no.

1. The defendant is convicted and sentenced after transporting methamphetamine.

The defendant, Mr. Marco Naranjo-Aguilar, drove a car containing

almost 50 pounds of methamphetamine. For this act, he was convicted of

possessing methamphetamine with intent to distribute. 21 U.S.C.

§§ 841(a)(1), 841(b)(1)(A).

To determine the appropriate sentence, the district court considered

the sentencing guidelines. See 18 U.S.C. § 3553(a)(4). These guidelines

allow the court to adjust the offense level downward when the defendant

played a minor role. U.S.S.G. § 3B1.2(b).

Mr. Naranjo-Aguilar requested this downward adjustment, alleging a

minor role as a courier in a drug deal. In support, he submitted a proffer

identifying three other participants. The court acknowledged the proffer,

but declined to give the downward adjustment. Without the adjustment, the 2 Appellate Case: 24-7050 Document: 56-1 Date Filed: 09/16/2025 Page: 3

guideline range was 235–293 months. Applying this range, the district

court imposed a sentence of 235 months.

Mr. Naranjo-Aguilar argues that (1) he should have obtained the

downward adjustment as a minor participant and (2) the sentence was

procedurally and substantively unreasonable.

2. The district court didn’t plainly err by denying a downward adjustment.

Mr. Naranjo-Aguilar argues that (1) the district court committed legal

errors in denying the downward adjustment and (2) the alleged errors were

prejudicial. We reject both arguments.

a. These arguments are reviewable under the plain-error standard.

Mr. Naranjo-Aguilar didn’t preserve these arguments in district court.

Granted, he did object to a recommendation in the presentence report

for the district court to deny a downward adjustment. But he’s appealing

based on the district court’s explanation, not what was said in the

presentence report, and he didn’t object to the district court’s explanation

for the sentence. So Mr. Naranjo-Aguilar didn’t preserve the legal

arguments that he’s making on appeal. See United States v. Yurek, 925 F.3d

423, 444–45 (10th Cir. 2019) (concluding that the defendant didn’t

preserve her challenge to the denial of a mitigating-role adjustment

because she was “alleging an error in the district court’s explanation”

rather than the “content of the presentence report”).

3 Appellate Case: 24-7050 Document: 56-1 Date Filed: 09/16/2025 Page: 4

Given the failure to preserve the appellate arguments, we apply the

plain-error standard. Id. at 445. Under this standard, we consider

• whether the district court erred,

• whether an error was clear or obvious,

• whether an error affected the defendant’s substantial rights, and

• whether an error seriously affected the fairness, integrity, or reputation of the judicial proceedings.

Id.

We conclude that (1) the district court didn’t err and (2) the alleged

errors wouldn’t have affected the defendant’s substantial rights.

b. The district court didn’t legally err.

In challenging the denial of a downward adjustment, Mr. Naranjo-

Aguilar argues that the district court legally erred by disregarding his

proffer and limiting the inquiry to participants who had acted inside the

judicial district.

The district court acknowledged the proffer, but said: “Absent any

knowledge or evidence to the contrary, the Defendant was acting alone

when transporting a large quantity of drugs in the Eastern District of

Oklahoma.” R. vol. 3, at 80. Mr. Naranjo-Aguilar interprets this sentence

as proof that the district court overlooked his proffer and disregarded

participants in other judicial districts.

4 Appellate Case: 24-7050 Document: 56-1 Date Filed: 09/16/2025 Page: 5

The district court didn’t need to explain why it declined Mr. Naranjo-

Aguilar ’s request for a downward adjustment. United States v. Nkome, 987

F.3d 1262, 1273 (10th Cir. 2021). But the court did provide an explanation.

So we must consider whether the explanation entailed a legal error. Id.

Mr. Naranjo-Aguilar argues that the district court overlooked

evidence consisting of a statement in the proffer that others had

participated. But what did the district court mean when it said that there

wasn’t evidence of others’ actions? We’ve said that “[a] proffer is not

evidence, ipso facto.” United States v. Reed, 114 F.3d 1067, 1070 (10th

Cir. 1997) (italics in original). 1 Given our characterization of proffers, the

district court might have meant only that Mr. Naranjo-Aguilar hadn’t

presented any testimony or exhibits identifying other participants.

Mr. Naranjo-Aguilar argues, however, that the district court

overlooked the proffer. This argument appears questionable, for the court

had referred to the proffer earlier in the explanation. Given this reference,

the court was apparently aware of the proffer when stating that there

wasn’t any evidence of other participants.

At most, Mr. Naranjo-Aguilar ’s characterization of the wording

suggests an ambiguity. The court might have forgotten that Mr. Naranjo-

1 Mr. Naranjo-Aguilar states that his “proffer or testimony is evidence.” Appellant’s Reply Br. at 2 (italics in original). But he doesn’t provide any authority for treating his proffer as evidence. And he didn’t submit any testimony. In fact, his proffer was not signed or verified. 5 Appellate Case: 24-7050 Document: 56-1 Date Filed: 09/16/2025 Page: 6
