Woodson has done, and brings quite a lot of good things to IU basketball. You've listed some of them on this thread, I'll add bridging the gap back to RMK...I think he was uniquely suited to help pull that off, and all IU stakeholders...the school, the fans, RMK and his family, the former players...all of them needed that. Big scheme, if Woody ends up falling short again this next year, and gets fired, for the above reason alone, his time at IU won't be a failure.
My main beefs... in no particular order...
He hasn't changed the roster focus, at all, since he arrived in Bloomington. Whatever the reason, justifiable or not, he's had 3 full offseasons to round out his rosters and program with higher level perimeter players, and every single year, we've been talking about needing better guards.
His teams don't consistently play hard, and they don't execute much of anything good consistently. So...consistency... Study basically any top sports program, in any sport, and the common thread is attention to detail, and mastering all the little details. There's is virtually no evidence that would show that Woodson is willing and/or capable of coaching those basic things well.
There are some other things like his substitution patterns, and how he handled X... But if he would improve those 2 main things I mentioned, I think he might start approaching being a solid coach at IU.
