Three things to look for:
1. Third down.
Tennessee leads the SEC with a 54.3 percent conversion rate. Alabama (51.1) ranks second. It has converted 60.7 of its third downs in four SEC games.
2. Rushing. Alabama leads the SEC with 241.6 yards rushing per game. Tennessee ranks last (89). Alabama leads the nation in rushing defense (38.1).
3. Passing. Tennessee ranks second in the SEC in passing (294 yards per game), but its best QB is out. Alabama leads the league in pass-efficiency defense. Tide opponents have completed only 48 percent of their passes, and Alabama leads the SEC in sacks (15).
