Georgia at South Carolina
5:30 p.m., ESPN
The Bulldogs have an embarrassment of riches at tailback, so much so that a former starter, Tony Milton, is now a backup fullback. They have a pair of talented quarterbacks in David Greene and D.J. Shockley. But Georgia is banged up on defense -- particularly at middle linebacker -- and allowed 28 points to Div. I-AA Georgia Southern. Plus, the Gamecocks thoroughly dominated what was supposed to be a rejuvenated Vanderbilt squad last week, and the 82,000 at Brice-Williams Stadium will be . . . uh, just a bit fired up. An upset is absolutely possible. Not probable. Possible. (How's that for a outside-the-hedges hedge?)
 Texas at Arkansas
8:45 p.m., ESPN
They have heard it over and over again in Austin. The Longhorns gave up 265 yards to Arkansas last year -- on the ground. They lost, 38-28. The defense was soft all season. Enter Greg Robinson, he of the resume that includes stops as a defensive coordinator with three NFL teams. Enter Dick Tomey, he of the resume that includes stints as head coach of Arizona and Hawaii. The new assistant coaches aren't there as decorations. If the Longhorns' defense is truly going to be better this year, it must start tonight against Arkansas QB Matt Jones, who was 13 for 16 last week against New Mexico State. And we must consider the fact that the Razorbacks have named a guy called Clyde "Smackover" Scott, a former Hog player, as their honorary captain tonight. That can only help Arkansas, right? Come on. "Smackover"?
 Utah at Arizona
Try this scenario on for size. The Utes romp tonight, handing Arizona's first-year coach, Mike Stoops, his first loss. Then what's to stop them from rolling to an unbeaten regular season? An Oct. 16 home game against North Carolina? Please. A two-touchdown Utah victory. A Nov. 6 game against Colorado State? Maybe, but the game's in Salt Lake City. The Nov. 20 showdown with rival BYU could be juicy, but let's say the Utes finish 11-0. We'll figure out quickly whether the BCS, in its current form, could allow one of the little guys into its party.
 Clemson vs. Ga. Tech
Forget FSU-Miami. This feels like a good ol' ACC game, with one team on the fringes of the top 25 and the other squawking meekly that it belongs. The game is actually much bigger for the Tigers, who are coming off a shaky-at-best double-overtime victory over Wake Forest, during which the Deacons gained 410 yards. People forget all too quickly how close Coach Tommy Bowden was to being canned last year. Only a miraculous victory over Florida State -- curiously coached by Bowden's father Bobby -- helped spark a four-game season-ending winning streak.
