What position groups are there to be worried about? It's less of a position group thing and more of a position issue.
MLB - Tymar Sutton / O'Rien Vance / Jake Hummel - One soph, 2 frosh
Star - Jatairas Grant / O.J. Tucker - One soph, one frosh
Safety shouldn't be on this list. I know people will ask about it, but I feel Wilkerson was solid but replaceable. And while KCM was good in run support, he struggled in the passing game, as noted by Jay Jordan. We have capable bodies there.
LG/RT - I think the offensive line will be much different by the start of the season vs what we think now. But I'm very excited about Bolton/Hudson. Need to see something from Meeker to really put the offensive line in a good place.
