No. 1 Texas takes its first road trip into Neyland, facing a true freshman QB who hasn't thrown a pick yet. Buckle up.

Week 4 is the loaded one, Yahoo Sports says: six matchups between AP Top 25 teams on Saturday, four in the SEC and two in the Big Ten. The headliner is No. 1 Texas at No. 14 Tennessee. Vols true freshman quarterback Faizon Brandon has nine total touchdowns and no interceptions through three games, and Tennessee ran 45 times for 299 yards against Georgia Tech. But Texas is allowing just 3.4 yards a carry. On the other side, Arch Manning is averaging under seven yards per attempt, and Tennessee's opponents have thrown for only 453 yards all season. Elsewhere, No. 4 Ole Miss is an underdog at No. 21 Florida, Iowa at Michigan carries the week's lowest over/under at 38.5, and Oregon visits USC. In Knoxville it's strength on strength: the Vols' ground game against a Texas front that hasn't budged. Win the line of scrimmage, win the day. That's football.
