He just won the BTT. No doubt that was a great run. His only tourney run... outside of making the NIT Final in 2013.
The "most wins in history" is more a by product of how long he's had the job. He also has the most losses in school history.
Before you leap to false conclusions, I'm not agreeing with O'Keefe...just completing the picture.
That said, some youth would be a good move. Kirk Speraw was great and Billy Taylor was a tough loss too, need to replace them with somebody good and younger. There are some great young assistants that could position themselves to be the next HC when Fran retires.
