After a wild first few weeks of the college football season, we may have our best slate yet in Week 4. Saturday features six matchups between teams ranked in the AP Top 25, with four of those in the SEC and the other two in the Big Ten.

The day starts with the marquee showdown between No. 1 Texas and No. 14 Tennessee in what is easily the biggest game of Vols QB Faizon Brandon's young career. Brandon has yet to throw an interception and has nine total touchdowns; can he outshine Arch Manning and the Longhorns?

The action continues in the afternoon as No. 4 Ole Miss looks to avoid a letdown after its big win over LSU. The Rebels are actually road underdogs against Jon Sumrall and the new-look No. 21 Florida Gators. In the Big Ten, No. 17 Iowa and No. 18 Michigan will meet in what will assuredly be a defensive battle. The over/under in the game in the lowest of the week at 38.5.

Then, in the evening, we have a trifecta of ranked-on-ranked matchups with No. 23 Texas A&M vs. No. 10 LSU, No. 20 Oregon vs. No. 12 USC and No. 19 Missouri vs. No. 24 Mississippi State. It's an action-packed slate that surely won't disappoint.
