I don't think there are any excuses when you have Garza and Joe W back along with solid role players in Connor, Pemsl, and Kriener. Add to that 4 star recruits Patrick and Joe T, a grad transfer to mitigate Bohannon's loss, and potential breakout stars in Nunge and Fredrick and you have no excuses. If we don't win 20+ games and make it back to the NCAA's with a roster laden with plenty of experience/talent and TWO coaches son's, we will have under-performed and I'll be very disappointed in Fran and the transfers of Moss and Dailey would weigh heavily against him. However, I don't think that will happen. Lots of moving parts, but I think Joe T can take over the point, Bakari can mitigate the loss of Moss, Fredrick can replace Bohannon's shooting, Nunge can be an upgrade over Cook with his combined offense and defense, Patrick can mitigate Baer's loss, a more experienced Kriener with Pemsl can definitely be an upgrade over only Kriener to relieve Garza and Nunge, and more experienced leaders in Wieskamp and Garza can have a better seasons. To me, this all points to at least a similar season as last year where we were only a few minutes of OT away from the Sweet 16.
A guy leaving early who is only boarderline NBA at best is a small excuse. But to me it's only an excuse for having a slightly worse season than we would have if Cook would have stayed. It's not enough of an excuse to miss the tournament altogether.
