Sometimes promoting from within works, and sometimes it doesn't.
100% SU will go in house when JB steps down. JB will time it so it has to be an in house succession.
But any in house guy usually only gets 2 seasons. If he has 2 poor seasons he'll get fired and then they go outside.
I would love to see the new HC, in house or not, change the style of play from 100% zone. Play pressure D and up tempo. (Like Oats would do). But with Red and GMac that likely won't happen. The key to winning in college ball is recruiting. I doubt elevating in any of our guys changes recruiting in a major positive way. The HC has to have energy and be a top notch salesman. Neither of our guys strikes me as that. Though at this stage both would probably bring more energy than current situation.
It doesn't happen often. Duke and UNC are doing it now and IMO both will fail. But they are bigger programs and are still at the top, so it will be easy to recover. UConn, Indiana, UNC, Oklahoma State all did it and it failed. Kansas, Illinois, Arizona, Cincy, Temple, Kentucky, Louisville all didn't do it and it worked out. Michigan State and Gonzaga did it and it worked. Oklahoma, UNLV, Mizzou didn't and it failed. Michigan, Louisville didn't do it and it is TBD but off to a good start. Wisconsin did it and it is TBD but not looking good. Maryland didn't do it but where do we put this? Failed because he was fired? Or worked out because the record was fine? Can you call getting fired a success? Can you call getting fired in year 11 a failure?
Inside Job
2-4-3
Outside
7-3-2 plus Turgeon who avg'd 10.5-7.9 in conference and 22-11 overall.
The outside hires have done better.
EDIT
And how can I forget Georgetown to the list of failures? Which brings that to 2-5 with 3 TBD. Also can we really count Few as they aren't a P5 school? They did not have the mean$ to go out and get a decent HC when he was hired. The HC before him left to go to Minnesota which would never happen now. So really in the last 40 seasons Izzo is the only one who worked out from a major program.
EDIT II
And we can also add St Johns to that list of failures (2-6 now). Shouldn't we learn from the failures of our rivals (GTown, UConn, St Johns)?
EDIT III
Need to add Nova too. This though is a lot like MD. It wasn't a complete failure but it wasn't really a success. Lappas improved the team vs the end of Rollie's tenure. But it wasn't enough and he was fired after 9 seasons.
