ARKANSAS AT ALABAMA
When: 3:30 p.m., CBS
Broadcasters: Verne Lundquist play-by-play, Gary Danielson analyst.
Line: Alabama by 15.5.
Why you should watch: Arkansas never has had a 3,000-yard passer, but it sure looks as if that will change by the end of the season. Ryan Mallett last week set the Razorbacks' single-game passing record with 408 yards and five touchdowns against Georgia. The Hogs' offense is much improved from the unit that was ranked 49th nationally last season, but Mallett has not faced a defense like Alabama's - which has allowed just four offensive touchdowns in three games this season. Arkansas' defense is, well, not dominant. The Hogs allowed Georgia quarterback Joe Cox to pass for 375 yards and five touchdowns.

CALIFORNIA AT OREGON
When: 3:30 p.m., ABC regional/ESPN GamePlan
Broadcasters: Terry Gannon play-by-play, David Norrie analyst.
Line: California by 7.
Why you should watch: Cal is the talk of the West Coast now that USC has suffered its seemingly annual Pac-10 road loss to an unranked opponent. That should worry Golden Bears coach Jeff Tedford, who has watched four of his teams reach the top 10 only to collapse late in the season. With more than 300 rushing yards in wins over Purdue and Utah, Oregon has recovered since its embarrassing season-opening loss at Boise State. But Oregon still doesn't have a TD pass. A former Ducks offensive coordinator, Tedford got the best of former boss Mike Bellotti with four wins in six meetings. How will he fare against new Ducks coach Chip Kelly?

MIAMI AT VIRGINIA TECH
When: 3:30 p.m., ABC regional/ESPN/ESPN GamePlan
Broadcasters: Sean McDonough analyst, Matt Millen play-by-play.
Line: Miami by 2.
Why you should watch: Is "The U" back? Miami fans say yes; they're already looking up flights and hotels on Priceline for a trip to Pasadena. Cooler heads say the next two games will be tougher than the previous two. Virginia Tech brings a much stronger defense than either Florida State or Georgia Tech. Opponents (including Alabama and Nebraska) have made 15 trips to the red zone against Virginia Tech, resulting in only three touchdowns. Virginia Tech has a strong rushing attack, but Tyrod Taylor still has some work to do as a passer - though he did throw a game-winning TD pass against Nebraska last week.

IOWA AT PENN STATE
When: 8 p.m., ABC
Broadcasters: Brent Musburger play-by-play, Kirk Herbstreit analyst.
Line: Penn State by 10.
Why you should watch: Iowa kicked a last-second field goal to beat the Nittany Lions 24-23 last season; it was the Nittany Lions' only regular-season loss and it almost certainly kept them out of the national title game. The rematch in State College doesn't appear to carry the same BCS implications; then again, that's because we don't have a great read on either team. Penn State has outscored its first three opponents 90-20 - but the first three opponents were Akron, Syracuse and Temple. Iowa barely escaped in its opener against Northern Iowa, but has looked more dominant in wins over Iowa State and Arizona. Freshman running backs Adam Robinson and Brandon Wegher have fared well for the Hawkeyes. Are they mature enough for a night game in Happy Valley? If Penn State linebackers Sean Lee (knee) and Navorro Bowman (groin) remain hobbled by injuries, that helps Iowa.

TEXAS TECH AT HOUSTON
When: 9:15 p.m., ESPN2
Broadcasters: Mike Patrick play-by-play, Craig James analyst.
Line: Houston by 1.
Why you should watch: With BYU and Utah out of the way, Houston has a chance to be a "BCS buster" thanks to its upset over Oklahoma State. The Cougars were off last week to calm down from that win in Stillwater. This could be the most pass-happy game of the season; both teams eclipsed 600 pass attempts, 5,000 passing yards and 45 passing touchdowns last season. Houston offensive coordinator Dana Holgorsen is a long-time disciple of Texas Tech coach Mike Leach. Holgorsen played wide receiver for Leach while he was offensive coordinator at Iowa Wesleyan; the two also coached together at Valdosta (Ga.) State from 1993-95 and Texas Tech from 2000-07. Also, Leach and Houston coach Kevin Sumlin are former Oklahoma offensive coordinators who moved from that role to head-coaching jobs.
