Son of Hall of Famer impresses and other top takeaways from final Senior Bowl practice

During a seven-on-seven drill, Rice continued his domination, recording a phenomenal catch over Notre Dame corner Cam Hart.

Arizona receiver Jacob Cowing's efforts negated by injury 

Cowing had a dismal first two practices, but shined for some moments during Thursday's practice. He had stellar footwork and route-running during one-on-ones, and continued to perform well during seven-on-sevens.

After making a nice catch on an underneath route, Cowing went down with what looked like a lower-body injury. He was helped off the field, and did not make another appearance. His time in Mobile is likely over: a very unfortunate ending for a player just catching on with the team.

UNC receiver Devontez Walker has another bad day

Walker was terrible on Tuesday, slightly better on Wednesday and terrible again on Thursday. He has looked to be miles below the other receivers, and his draft stock should tank following his time in Mobile. 

Although fast with good route-running capabilities, Walker's hands have simply not been good enough. He dropped a number of passes Thursday and practices prior, which scouts certainly took notice of.

Oregon quarterback Bo Nix bounces back

Nix had a rocky first two days, but Thursday was his redemption day. He made a number of nice throws to several different receivers, and he looked like a leader while on the field, visibly realigning players and helping teammates navigate through the new offense.

How Nix performs on Saturday will be the telltale sign of his status, but he seems back from the odd slump that took place earlier in the week.

South Carolina quarterback Spencer Rattler outperforms other American Team quarterbacks

Out of quarterbacks Michael Pratt from Tulane, Joe Milton from Tennessee and Carter Bradley from South Alabama, Rattler looked the best on Thursday.

He made a number of nice throws during seven-on-sevens — one a back-shoulder fade to Louisville receiver Jamari Thrash that counted for a touchdown, and the other a similar back-shoulder fade that went right through the hands of the intended receiver. Rattler additionally made nice off-platform throws  — which he excels at — and had great footwork in the pocket throughout the day. 

The other QBs saw less success. Milton's superior arm talent was clear during warm-ups, but it did not translate to in-game action. He was picked off in the end zone on a poor read, and overall did not do anything spectacular. Pratt had some nice plays sprinkled into his day and showed some impressive arm talent, but there was nothing from him to write home about. Bradley was surprisingly solid considering his lack of collegiate recognition, but did not come close to dethroning Rattler.

New Hampshire running back Dylan Laube continues to shine

Laube entered Mobile as an under-the-radar, unknown player. He will leave Mobile a fan-favorite and coveted draft prospect.

Like the first and second days, on Thursday, Laube's hard-working, gritty personality was evident. He was the first player on the field, and one of the hardest workers during each drill. He ran great routes out of the backfield during one-on-ones, and continued his strong work during goal-line 11-on-11s, where he racked up a bundle of rushing and receiving touchdowns. For those tuning into Saturday's game, Laube will be one of the main guys to watch. 

Toledo cornerback Quinyon Mitchell's shoes left unfilled

Mitchell — one of the top cornerback prospects for the draft — was absent Thursday, but nobody on the National Team really stepped up and proved they were the next-best thing. Some solid one-on-one reps showed Cam Hart was the most tuned out of the remaining group for that day — with Rutgers CB Max Melton a close second — but it was disappointing to not see a clear standout.  

Two different days for Georgia receivers

Thursday, Ladd McConkey continued to dominate his opponents. He was electric in the one-on-ones that took place towards the end of practice, and also stood out during individual wide receiver drills. He was quieter than expected during drills that involved the full offense and defense, but for the vast majority of practice, he was electric. 

Fellow Bulldog Marcus Rosemy-Jacksaint saw much less success than his teammate McConkey. Similar to Walker, Rosemy-Jacksaint was fine when it came to getting open, but couldn't finish the play with his hands. One of his drops during seven-on-seven resulted in an interception, and another drop came a few plays later during the same drill. It has not been a great time for Rosemy-Jacksaint in Mobile.
