Even if Jaelan turns out to be better than a projected top 10/15 pick (a big IF), we're certainly not better without Greg. Given the tempo and pace of modern CFB, our 4th DE is important and will get a significant amount of snaps. Instead of Harvey getting those snaps, now we're gonna rely on Cameron or Chantz. Of course, all of this is still assuming that none of our DEs get injured or get Covid.
Greg is not the best player who ever or will ever play at UM. I don't want to fold the program because Greg is sitting out. We could still win a lot of games without Greg. But it's pretty obvious we will be worse without Greg. If Jaelan ends up being better than Greg, then certainly a good portion of that loss will be minimized, but having 2 top 15 picks makes you better than having 1 top 15 pick and vice-versa.
