This is the 2016 NFL Combine Stock Report for the running backs. Follow me @walterfootball for updates.
Tyler Ervin, RB, San Jose State
Tyler Ervin was expected to post great numbers at the Combine, and he definitely didn't disappoint. He ran a 4.39 unofficial 40 with a 1.56 10-yard split, and he also posted a 39-inch vertical and a 10-10 broad jump. Ervin was more than a workout warrior, however, as he flashed some great receiving ability in the drills.
Derrick Henry, RB, Alabama
Derrick Henry got off to a shaky start, weighing seven pounds heavier than expected. Henry said he was "surprised" about this weight gain, which seemed puzzling to me. However, he more than made up for it on Friday, posting a 37-inch vertical and a 10-10 broad jump. He then was timed with a 4.54 40, which was a strong number for his size. Henry, who made a great catch in the drills, still isn't guaranteed to be chosen in the first round, but he definitely helped his cause.
Keith Marshall, RB, Georgia
Tony Pauline reported that Keith Marshall would time extremely well in Indianapolis. He was right, as Marshall blew everyone away with an unofficial 4.29, which ultimately turned out to be an official 4.31. Marshall messed up a bit in the drills, but he definitely put himself on everyone's radar, flashing some great potential. Marshall had injury issues in 2013 and 2014, but if he can stay healthy, he could make something of himself at the next level.
C.J. Prosise, RB, Notre Dame
C.J. Prosise is a skilled runner who tested extremely well. He ran a 4.46 40 and also notched a 35.5-inch vertical and a 10-1 broad jump. He flashed in the drills as well, especially as a receiver; he caught the ball very naturally. There's a chance Prosise will be chosen in the second round.
Kelvin Taylor, RB, Florida
Kelvin Taylor, son of former Jaguar great Fred Taylor, did not have the sort of Combine performance that was expected of him. He ran slowly (4.60) and then went on to drop countless passes in the drills.
