Here's a contribution from reader/commenter ironman4579, who went back and tallied Michigan's spring game statistics. There are a few somewhat minor differences between his and those from Rivals that I posted last week, but he adds a more specific breakdown that might be interesting to you. Kudos to him for his work:
I messed up somewhere on QB rushing, so I haven't included those numbers. I've included a passing breakdown of short (under 10 yards) intermediate (10-20) and long (20+). The yards after catch and run after catch numbers might seem off (Mike Cox has more yards after contact than yards), but I went with the place a guy was first hit (or caught the ball) as the starting point. Obviously if he was hit 3 yards in the backfield, and managed to get back to the original line, he shouldn't get 0 YAC. Also tackles are basically just the guy I felt was "most" responsible for the tackle. I didn't break it down into half tackles or anything. The receiving numbers should be off by one. Gardner completed a pass to a guy that I never got a look at.
As a final note, I only included the guys that we all actually expect might see some time this year, or were at least somewhat well known prospects. The odds of a guy like Teric Jones seeing much action probably aren't great.
