Record: Justin Ernest, Defensive Line, 1999 (51 reps at 225).
Having success doing bench reps in Indianapolis doesn't necessarily translate to success on the football field on Sundays. Ernest, a former Western Kentucky defensive tackle who holds the record, never suited up in the NFL.
Despite that, strength is invariably important, mostly when scouting interior line prospects on either side of the ball. In particular, two defensive tackles could challenge Ernest's record this year.
Star Lotulelei of Utah is the No. 1 overall player on many expert boards. He's talented and can play in both the 4-3 and 3-4 schemes, and he strikes me as someone who can put all he has into this specific workout.
At 6'3" and 320 pounds, Lotulelei possesses a ton of natural upper-body strength. He can throw blockers off the line while holding double-teams at bay in the middle of the field. It will be interesting to see what he does in this week's workouts.
Meanwhile, Brandon Williams from Missouri Southern is one of the most impressive small-school prospects that I have scouted. Heck, he may be one of the most impressive overall players I have watched on tape.
The Division II All-American stands at 6'3", 325 pounds and has athleticism we rarely see from someone his size. He can anchor the interior line and even get to the quarterback, as evidenced by the 8.5 sacks he recorded as a senior in '12.
As it relates to this specific workout, Williams has the upper-body strength and stamina to go the distance. It wouldn't surprise me to see him challenge for the record.
The consensus No. 1 overall guard in the draft, Chance Warmack, is also someone to keep an eye on here.
