I could see Beilein being really good... but I could also see it going very poorly. If it were to take him 3-4 years to rebuild us he would be 72 years old or so. Not many coaches continue into their mid 70's and so I think its reasonable to expect that he would bring in a top assistant(be it Fife, Cheaney, Smart, whoever) as the head coach in waiting. But what happens if Beilein isn't as successful as we would hope? Does the top assstiant still get the job? Or do we look elsewhere yet again?
I don't know, but if it were my money, I would much prefer someone like Beard, Drew, Musselman, or Oats who we could expect would stay for a long time if successful. Every time we change coaches its a gamble despite how much of a "sure thing" the hire is(as we have seen over the last 4 years). Hiring Beilein means hiring another coach within the next decade which is just more increased risk.
