This is partly right .. the issues a WR may be just fine if potential does what potential can do but we just don't know. Two 5*s coming in (I know, Blaylock lost his at the end after being the star of AA Game somehow), Cager as a transfer from Miami, and 4 and 5 stars in Simmons and Robertson so if they play up to their potential, great, if not ...
On the DL, there are no questions there so can't figure out where the heck you got that from. With Tyler Clark, David Marshall, Beal, Herring, and Jordan Davis clogging the middle, Adam Anderson and Brenton Cox coming off the edge and a slew of new guys on top of that, this is NOT a concern for UGA at all and won't be fun for opposing OLs for the next few years.
As far as QBs go, I wouldn't go there as long as you have Felipe Franks and his might face chinchilla running the offense.
