Seems like a similar argument that we were having when Greg Elliott was the hot name: take the bird in the hand, or wait for the pterodactyl in the bush. Except Id argue that both Alstork and CJ are more valuable than adding Greg, especially since it seems we may have just one more year of DJ+Mo. Ignoring trying to guess just how likely it is that Bamba or one of the grads chooses Michigan (i.e. putting a % chance on it), because that seems like a crapshoot, I see the possible outcomes as:
Bamba likely makes us a trendy top 10 pick (especially if both DJ and Mo are back), with unlimited upside. He would be the face of the program for at least a year, and possibly swing our recruiting into a real asset.
Either grad transfer probably solidified us as a top 1/3 B1G team, with room to outgrow preseason expectations.
