Michigan coach Brady Hoke says there was a lot to dislike in his first preseason practice with the Wolverines.

Hoke identified about 15 things he wanted done better, adding he's hard to please because he wants the best.

Rich Rodriguez's replacement has generated a lot of excitement. Hoke, though, says he knows there's a lot of work that has to be done to match the hype when it matters.

Michigan's biggest problems are in the kicking game and on defense.

Hoke says freshman Matt Mile may kick and punt, filling in for suspended punter Will Hagerup. He will miss the first four games for violating unspecified rules.
