The workout wonder of the day was Auburn's Greg Robinson, who followed up his strong performance in the bench press (32 repetitions) by covering the 40-yard dash in 4.92 seconds, impressive for a 332-pounder. Robinson also has the fifth-longest arms of any offensive lineman at the Combine (35 inches). Although Robinson is not the most refined blocker at the Combine, his skill set and size could project him to left tackle, and could enhance his chances of going high, given that position's premium status. Robinson was also the only offensive lineman to reach 30 or more bench-press repetitions and run a sub-5.10 40-yard-dash.
Another strong workout belonged to Michigan's Taylor Lewan. Among the offensive linemen who did the five core drills at the Combine -- bench press, three-cone, short shuttle, broad jump and 20-yard dash -- Lewan was the only offensive lineman to finish in the top 10 in all of them. He had the best 40 time (4.87 seconds) and broad jump (117 inches), and was no lower than eighth in the categories, for an average ranking of 4.6.
Nevada's Joel Bitonio would have been in Lewan's territory with a better bench-press figure; his 22 repetitions placed him 27th of the 35 offensive linemen who lifted. He was in the top three of all other categories, for an average ranking of 7.2.
The fifth-best average ranking belonged to Texas A&M's Jake Matthews (10.2), who did nothing to hurt his lofty stock. finishing among the top 10 offensive linemen in the 40, the three-cone and the short shuttle.
The outlook was not as positive for Alabama's Cyrus Kouandijo, a 6-foot-5, 310-pound tackle who has generally been projected as a mid-to-late first-round pick. He had the slowest 40-yard dash time (5.53 seconds) and the second-fewest bench-press repetitions (21) amid reports -- including one from NFL.com -- that he failed multiple team physicals. That news has the potential to be far more damaging than anything he did -- or did not do -- during his workout.
Among tight ends, Dixie State's Joe Don Duncan helped enhance his credibility as a blocker by racking up 35 bench-press repetitions, seven more than any other tight end and more than all but two offensive linemen.
Tennessee State's A.C. Leonard turned heads with a 4.5-second 40-yard-dash time, but North Carolina's Eric Ebron had the best blend of speed and power; he was the only tight end with more than 20 bench-press repetitions (he had 24) to run the 40 in less than 4.7 seconds (he covered it in 4.6 seconds).
