I would think Locklear would get a shot at center, no? Only reason i think Niehaus isnt done (only comparing Hall and Niehaus right now) is that Niehaus is retweeting UT stuff daily, things Niedermeyer has said, etc. Hall barely has anything at all related to UT football. I know that isnt much to go on but what else is there since no insiders know anything about these two.
EDIT: not retweeting daily, but at least several things in the past week. Also, you meant Tatum is the third tackle as in third in line behind Richmond and Smith correct? Once more off season of weights and eating, and hes finally a halfway decent tackle in the SEC. not faulting the guy, but them SEC DEs are big kids.
