Pretty much everyone on the board though burning KoVien's redshirt was a good idea at the time:

A lot of people were still upset about ANO's transfer and thought that redshirting at all, no matter the circumstance, was a bad idea. Perhaps Mooney thought the same thing. As for the number of transfers, 2 a year is the average per team in D1. It will hurt us more than usual since we don't have 13 scholarship players, but it is the norm now.
As for PF, Darius Garret played only 81 minutes his first year. PF has played less than that, but both amounts of playing time are really small. I think PF will have a chance to get meaningful minutes as his career progresses, the fact that he hasn't played much is not a good sign though. From what we have seen there is no reason to believe his offense isn't on an A10 level, I suspect his defense is what has kept him from the floor. I don't think he transfers, and unless Golden is really good I wouldn't be surprised if Paul gets 10+ minutes a game next year.
