1: He's had great recruiting classes. This is a reloading season. They have a very young team that can be great next season.
2: The reason is very simple why people think that. Jim Harbaugh is a great coach, during his time in the NFL before he went back to Michigan. He was the one that coached San Francisco to reach the Superbowl not that long ago. Despite that loss he deserved some credit... It's funny how time flies and see San Francisco still struggling currently now.
3: Because of the recruiting (Number two class last year) and because he has more experience as a coach than Hoke as he coached an NFL Team
