Sign Parrish as an athlete, move him around, some thunder-lightning RB, some slot, some WR, some KR.
If he can't make Chaney or Knighton transfer in the next few years, then he can find more PT elsewhere.
Look, setting aside emotions, if Parrish wants to win games and go to ACC championships, then logic tells you that Pitt is the better choice.*
