The University of Michigan held their Pro Day on Friday, March 18th and the New England Patriots were present, per NFL Draft Insider Tony Pauline.
Michigan defensive tackle Willie Henry is rated all across the board, but his 6'3, 305 lbs frame and 5.00 second 40 yard dash warranted additional focus. Henry is an explosive player with tremendous upside due to his age (21 this March). He's a versatile player and the Patriots apparently expressed interest.
The Patriots also worked with Michigan linebacker Desmond Morgan. The 6'0, 230 lbs Morgan ran slow 4.81 second 40 yard dash, but his 6.85 three cone time certainly caught the Patriots attention.
Pauline also heard that "most of the teams in attendance" met with Ferris State defensive tackle Justin Zimmer. The 6'2, 300 lbs Zimmer put up 44 reps on the bench and showed his explosion with a crazy 9'9 broad jump. His 40 yard dash was timed in the 4.8-4.9 range and his three cone was a hair over the 7.10 second mark. He's an athletic phenom that would be worth a day three draft pick.
Possibly the star of the Pro Day was Eastern Michigan running back Darius Jackson. The 6'1, 220 lbs back ran the 40 yard dash in 4.35 seconds and added a 41" vertical, 11'1 broad jump, and 6.82 three cone time. He's a physical specimen and picked up 1,289 yards from scrimmage this past season, including 21 receptions. He definitely worked himself into draft consideration.
