My 2 cents. I haven't read all the posts in this thread, and this is long so feel free to ignore.
To me, 2 things have been pretty obvious over the last 2 decades:
1. No matter how great a program you are, you're probably going to drop off after a coaching legend leaves.
2. Even if you make the wrong hire when you replace your legend and drop off, you can bounce back quickly if you make the right hire the next time.
Pitino left Kentucky, Tubby took over and had great success with Pitino's recruits, then had less success, got fired, and Billy G took over. He of course was a complete disaster, but they hired PayPal and bounced right back.
Dean Smith left N.C. Bill Guthridge took over and had success with Smith's recruits, then he retired and they hired Matt Dougherty, who was a complete disaster. But they bounced right back with Roy.
Same with Indiana; Knight, Mike Davis, Crean, etc. Although Crean took a few years.
Those are 3 of the "big" 6 programs in college basketball history. To me there is no shame to me in having less success initially, because even the all time great programs have proven it's likely, but I understand if people feel differently.
I'm also of the belief that people value 1-2 years of good NCAA tournament results waaaaayy too much. There is just such insane variance in that tournament, and if any program should realize that it should be us. We went 49-5 in the Big East regular season the 3 years Ray was here and never even made the Final Four. Then last year 9-9 and bink, 3rd National Championship. It defies logic to some extent.
Brad Stevens made back to back championship games, but was one of the craziest plays I've ever seen in my whole life away from losing in the 2nd round. Would he be valued as highly if Nasir Robinson hadn't made an idiotic foul? Probably not. Shaka Smart's VCU team probably didn't even deserve to be in the tournament last year based upon their regular season resume. If they don't get in last year, do we even know who Shaka Smart is? Probably not. This isn't to say these guys aren't great coaches. They may be. They also might not be. Kevin Ollie isn't a sure thing. Neither is Mike Hopkins at the Cuse. Or Shaka or Stevens. There are no sure things.
So given that I would rather see Ollie get the job, because he's family, he's everything that has ever been great about UCONN basketball, it's what JC wants, I love him, and even if he fails it's been proven we can bounce back with a good hire post Ollie. We'll be able to leverage a brand new practice facility and 25 years of greatness on the court, and we'll get whoever the new "Shaka Smart" is 5 years from now. Because there will be someone, it's just how it works.
