Lorenzo Jerome's stock has fallen based in part on his 40 time:
Lorenzo Jerome, Saint Francis, S, 5-10, 204
Coming off terrific postseason performances at the NFLPA Collegiate Bowl and Reese’s Senior Bowl, there was growing buzz surrounding Jerome. But with him lacking in height, NFL personnel wanted to see Jerome post a solid time in the 40, and he didn’t while running in 4.73 seconds and his official 4.70 mark. He’ll seek to lower the slow time at Saint Francis’ Pro Day on March 16. The Red Flash haven’t have an NFL Draft pick since 1945.
