re: Cornell, Joy and Cerchio are coming off of greyshirt. Joy probably has to beat out Cornella at 141 (I hope Cornella is back, anyway) and/or Fernandez at 149. If he doesn't/can't get into the starting lineup he's probably not an impact freshman. Cerchio almost certainly slots in for Ramirez at 165.
I'd be pretty surprised if Knox, Perentin, Elijah D. the Cortezes, DeJesus, Correa and Dellagatta didn't all greyshirt this year. The big hole in the lineup is 184 and I don't see anyone on that list (or even coming off of greyshirt) who fits the bill.
