What happened: Tennessee is seven games into a season steered by true-freshman quarterbacks Faizon Brandon and George MacIntyre in an unsettled rotation. Jim Knowles, hired away from Ohio State by Josh Heupel, directs the conference's top scoring defense. South Carolina reopens SEC play in Columbia with Kendal Briles leaning on the run against a front that has conceded ground yards.

Why it matters: The matchup tests South Carolina's ground efficiency against the only SEC defense holding opponents under 160 passing yards per game. Protection decides the other side, with Tennessee averaging over four sacks per game against an offensive line facing its stiffest passing-down test.

What to watch: Wednesday's injury report should clarify quarterback availability for the weekend rotation. Watch early run calls from Briles and whether Sellers can escape Tennessee's pressure.
