The youtube search I have that usually turns up Michigan State fans in gorilla costumes and ads for illegal streams has hit upon something actually interesting for a change: cut-ups from the Michigan coaches' clinic.
This one is on Michigan's perimeter blocking:
Hit up 25 minutes for always-entertaining editions of the Michigan drill
The good blocks are widely distributed between Roundtree, Gallon, and Dileo with some cameos by Gardner(!) and Darboh. Darboh just buries a couple guys; Dileo and Gallon bring that Martavious Odoms mountain-goat-style blocking to the party. These clips are just the good bits, for the most part, but it seems like Michigan likes what they have in that department this year. Gallon in particular is ruthless in his desire to put guys on their ass 40 yards from the play.
Darboh should be an asset, as he's got a lot more size than anyone they played last year save Gardner and seems to have the same desire the mighty mites do.
The second item is about 5 minutes of individual WR drills featuring everyone's favorite training landmark:
The big takeaway there is the huge agility gap between Jackson and Darboh/Chesson, let alone the slot-type guys at the top of the depth chart.
