I always appreciate hearing the perspective of Eleven Warriors as regards Michigan. That whole thing about keeping close to your enemies applies here.
It is hard for Michigan fans to predict what the current season will bring. As a long time follower of Michigan football, I will say that Michigan fans were spoiled by many years of success. Being down for some time is not easy. I am one of those who attribute many of the problems to the woeful OL recruiting under RR. If you were really interested, you could look to several years where OL recruiting was abysmal. And once your line is gone, you're sunk. It takes years to build a solid OL & DL. Honestly, I still think Michigan is a year away from having both talent and experience in line play on both offense and defense. Having a bad interior line just ruins any kind of running game.
Because the OL is still young, I believe that Hoke isn't particularly on the hot seat in 2014. If Michigan wins 9 games, that will be ok this year. The real test comes in 2015 and 2016. If there is improvement in 2015 (while breaking in a new QB,) and even more improvement in 2016, Hoke will be set.
Regarding comparisons between Hoke and Urban, I don't think enough information is available yet. Certainly long term, Urban's record is much, much shinier. However, I think that Urban came into a much better situation (in terms of the recruiting cupboard not being bare.) And, to be sure, while Urban has done well during the regular season, the post season and Big 10 championship record in 2012 and 2013 has to be disappointing for Buckeye fans.
