Weiszer has the details here.
Ken Malcome is currently sitting at fourth string, behind Brandon Harton. Hugh Williams is your back-up left tackle, although per Weiszer, “Richt said that Kenarious Gates will be the first option at tackle if either Cordy Glenn or Justin Anderson goes out.”
You’ll find a few other less than familiar names sprinkled throughout. Obviously, it’s a long way until September 3rd, but I think it’s pretty clear the welcome mat has been laid out for the Dream Team.
