JH is a very good coach and it will take 3 years for him to turn it around. This late hiring time has screwed this years class but the next 2 Michigan will be in the top 3 recruiting classes of the big ten
JH brought in six 4 stars in this class. Nebraska only has three 4 stars in this class. The numbers may be low for Michigan in this class, but they have quality. I argue that the Michigan class is better than Nebraska's
Of course he did. He's Jim Harbaugh, and that name alone will be enough to stockpile his 2015, and 2016 classes with highly rated players...
If I was a recruit, he would have to make me feel comfortable about his longevity. I'm just not convinced he will be there very long.
I would also argue that Michigan in general is more inclined to attracting 4* recruits as there are many more populous states surrounding it than Nebraska. When Hoke was around, I believe he got more 4*s than Pelini despite Hoke not being a great coach. It's no different than many of the SEC schools having an easier time landing 4* recruits due to geography.
That is what Riley is going to try and help fix for 2016 and beyond. I think the goal for NU given its geography should be a top 20 class year in and year out. That should be enough talent to win championships with.
