As linked by TomVH's twitter, there are lots of good 1 on 1 drill videos that you can check out featuring many Michigan commits and prospects.
There's a run blocking 1 on 1, pass rush 1 on 1, RB vs LB, and WR vs DB.
The Michigan interest is mainly in the linemen drills, as we had no commits in the WR or RB video, and no targets with the exception of Dwayne Stanford.
In the linemen drills, however, Mario is small but impressive. He blows by Zach Banner at one point, who is about double his size. Aziz Shittu, Danny O'Brien, and Sheldon Day are other DL that were impressive in the drills. Joshua Garnett, Banner, and Erik Magnuson are the main targets on OL.
Just some fun videos to check out of some of the best high school players in the country
