I think the latest example is Brandon Crawford. He was great as a soph and seemingly a decent pro prospect; now it looks like he'll be back for his senior year.
I attribute the regression to the pressure of playing in the ACC against some of the best, if not the best, competition in the country. It is easy for 3 and 4 star players to lose confidence playing against the opposition's 4 and 5 star players. Nothing like having a Spalding (or whichever company presently manufactures the college ball) swatted back in your face. I remember having it done to me by no star players. I welcome other views.
