First off, I happen to think the 2010 defense will be, in many ways, a better and more consistent unit than we saw last year- even having lost DW and BG to the NFL. I look at the depth and consistent talent across our line, our experienced LB core* and the presence of Woolkfolk on the back end as legitimate strengths. Although it may be difficult to see past the horrific secondary play we've seen the last couple years, I truly believe it had a lot to do with our equally-horrific LB play and an inconsistent line, void of any depth, that relied too much on BG and an undersized true freshman (Roh) to make plays on every down (compounded by the fact that our offense couldn't stay on the field, but that's another story).
With that said, I am rather bummed that Demar will not likely make it to campus this fall because I remember the impact Jai Eugene had on Michigan football by landing in the SEC. Had he not been scooped up by Les Miles, he would have been starting opposite Leon Hall against Ohio State in '06. He would have been on the field in the second half of the Rose Bowl when USC decided to pass on every down. He would have been defending one of Armanti Edwards' myriad targets against App. State. The list goes on...
Of course no one player will ever make-or-break Michigan Football, but it would be foolish and revisionist to pretend his absence is anything but a huge blow. The kid is a special talent despite being a product of the ESPN/UA hype machine and he would have been playing for us against UConn in some capacity. Hopefully Denard will continue to have success, thus keeping UM on Demar's mind and showing him the benefits of working to make it to Ann Arbor.
The last thing I want to see is some SEC school swoop in and show him how much quicker he'd see the field if he didn't have to worry about... anything... but game day.
* I cannot believe that Obi and Jonas will continue to regress. Each has shown enough potential, and GR has such a proven track record of coaching LBs, that expecting a noticeable leap is quite reasonable IMO.
