I'm surprised this wasn't posted and part of it is behind the paywall but it's a good read about anonymous opponents and their thoughts on M's 2010 defense.
"The two things I always notice about defenses is if they're rallying to the ball - because then everyone is on the same page - and if they're hitting you hard. They'll really hit you with everything they've got if they're confident their teammates will have their back if they miss. I didn't see Michigan doing either of those things last year.
"That'll be the first thing I look for this year. If they've got five, six, seven guys in on every tackle and when they get to the ball, they're giving you everything you've got - that's when I'll know it's different."
Should be fixed this year.
On U-M's defensive line: "I felt bad for Mike Martin. He was the best defensive lineman in the league last year, for me it wasn't even close, but on that defense he wasn't going to put up numbers and he didn't get any recognition. But poll the guys that played against him and I bet 80 or 90 percent would say he was the best.
Woot. If BWC can produce and M can get some rotation the line should be very effective.
It's an interesting read, sad but all the problems/critiques form M's opponents are fixed or getting fixed which gives great hope for a good 2011 defense.
It's behind the paywall but I found it by going here first:
Then on the right hand side its under the title heading.
