Michigan offensive tackle Taylor Lewan raised his draft stock Saturday morning with an official time of 4.87 in the 40. Lewan, at 6-foot-7, weighs 309. 

He was the speediest offensive lineman.

Auburn’s Greg Robinson, who is 6-foot-5 and 332 pounds, had an official 4.92 after a false start. 

Michigan’s Michael Schofield, who is 6-foot-6 and 301 pounds, ran an unofficial 5.01.

Those are blazing speeds for offensive linemen that size.
