My biggest concern would be how much of his success can be attributed to Balkich and the move to the Big 10 from the ACC? Assuming he didn't run guys off, his 2 most successful seasons would have been comprised of Jr's and Sr's recruited by Bakich. He's doing well at Michigan now and has the Clemson and Vandy ties so he's been around good baseball.
My biggest fear as well. I did look at the roster and stats and the contributors those years were the kids recruited by Balkich. No question which of the two I would chose...the man that actually did the work...Balkich.
