That Bo took a cream puff Michigan team and transformed it into top 5 team within 2 years. Under Chalmers, Michigan was a near .500 team through the 60s,'64 was a lucky season due to the play of Timberlake at QB. OSU thumped them in Chalmers final year. Sometimes a great coach and his staff can transform a team quickly. That '69 upset really helped recruiting but also not having a limit on scholarships helped as well. But I was kind of amazed at how fast Bo turned Michigan around.
Very talented coaches and their staffs can turn around programs fairy quickly, even though their players are young. I was kind of hoping Hoke would take this trajectory but I still think he should be given through the 2015 season before we throw in the towel on him. I think that the odds are 70/30 that Hoke will be a good coach and get back to winning 10 games per season with plenty of BCS bowls, winning the B1G every third year and perhaps winning a National Championship in the new playoff format. If we are still loosing 4 games per season in 2014 and 2015, then it may be time to look for another coach.
