Keelon Brookins is really fast. I'd imagine he'll end up a CB.
I don't know who is a Gopher lock, but I know there are a lot of good DE / LB prospects next season.
A guy I really like is Chris Wipson out of Wayzata. He is progressing into a really good football player. As a SO, he started on a terrific Wayzata football team (a lot of really good defensive players wouldn't start at Wayzata as a SO), he looked good. As a JR, I thought he was the best player on a really good Wayzata defense. I actually think he stood out more than any defensive player on the field in the State Championship game. I don't know how well he can run or what his size really is, but if he is 6'3" 225 lbs and can move decent (appears to), he has a real chance to be a Big 10 football player.
There is also a kid from Eden Praire, a DT named Renke or something like that, he looks pretty decent.
Then there is the early big names:
Michael Flowers - DT - Humboldt
Keelon Brookins - DB - Tartan
James Onwualu - RB/WR/S - Cretin
Steve Schindler - LB - Hutch
(I don't know any outstate guys)
