MOBILE, Ala.— For Princely Umanmielen, good is not good enough. That rep could have been faster, that tackle could have been harder, that game could have been better, that whole season could have been better. There is always another step that can be taken to achieve greatness.

It's how he felt at seven years old, the first time he picked up a football.

"When we moved to Austin, Texas, me and my brother, we never played football before, and we didn't know how to catch," Umanmielen recounted, "so we asked our parents to buy us one, and they bought us one and how we learned how to catch is we stood very, very close to each other, threw the ball, took a step back, throw the ball."

It's how he felt after the first session of the 2025 Reese's Senior Bowl practice, despite a day when he couldn't help but stand out in drills.

"I feel like it went OK," Umanmielen conceded after the American team session on Tuesday. "I could have done better. I'm just looking forward to improving."

And it's how he felt after four years at Florida, despite having 98 tackles, 15 sacks, and three forced fumbles in that time, earning an invite to the Senior Bowl—a selection of 150 of the top college prospects who are draft-eligible—at that time last year.

"I just, I didn't feel satisfied."

So Umanmielen decided to use his final year of eligibility and enrolled at Ole Miss. While there, he picked up 37 tackles and a forced fumble. More importantly for the pass-rusher, he finished with 10.5 sacks. The double-digit total was his goal when he returned for a final season.

"I know what kind of player I am. I know I can finish off a season with 10-12 sacks, so why not do it? So I came back to college because I wasn't satisfied, and I needed a double sack season, and it happened," Umanmielen said.

"It was just my mindset. I can't move on to the next phase of my life feeling unaccomplished in the last phase."

With said double-digit sack season under his belt and the attention of all 32 teams in Mobile this week, Umanmielen is ready to move on to that next phase. Unsurprisingly, he knows there are still steps to take up that learning curve. Luckily for Umanmielen, that's the only way he's ever known to approach the sport…and he's fast enough to get up that curve quickly.

"So far, since we've been learning this week, the game goes really fast, and I think I play fast, so I think my speed can translate really well to it," the outside linebacker explained.

"At Ole Miss, we did a standing 10-yard, like, the 10-yard split in the 40-yard dash. I had the second fastest on the entire team. The first fastest was Trey Amos, a corner."

The speed tracks (pun intended). Umanmielen began his career on offense as a running back—"I have a lot of scars on my legs because I played tackle football with no pads on outside in my neighborhood and like it was a lot of times like nobody could tackle me," he laughs—before being switched to receiver. When he hit a growth spurt, coaches switched him to middle linebacker.

When he continued to grow, inching closer to his current 6-4, 255 pounds, it was clear his size and speed were made to be a pass-rusher.

That means there is still some unfinished business in Princely Umanmielen's career, and as he prepares to enter the NFL, it's on his list of things to accomplish.

"I still wish I could get in there a little bit; I've never scored a touchdown in my life. It's crazy."

That'll be the next step to take.
