Oklahoma vs. Texas
This year’s Red River Rivalry battle at the Cotton Bowl has more marquee value than in past years; as for the first time since 2004 both teams will enter the game ranked in the top five. Heading into this season, the Longhorns offense was thought to be their biggest strength. But it has been the Texas defense that has provided most of the swagger. The Longhorns are ranked fourth nationally in total defense and that is a big jump since the 2007 unit set a school record for most yards allowed in a season. They will get stiff competition come Saturday against top-ranked Oklahoma. The Sooners are in the top five nationally in all offensive scoring categories, led by the nation’s second-rated passer Sam Bradford. National coverage begins Saturday at 12 PM ET on ABC.

LSU vs. Florida
“The Showdown at the Swamp” marks the first time the last two national champions have faced each other since Notre Dame defeated Miami, 29-20, in 1990. The stakes are high for both schools; Florida must win to maintain any realistic hope of staying in the hunt for a berth in the BCS championship game, while LSU needs the win to stay on course to repeat as National Champions. And the matchup got even more intense after Tigers defensive lineman Ricky Jean-Francois promised that the LSU defense will try to knock Gator quarterback Tim Tebow out of the game. Later in the week, Jean-Francois said his comments were misinterpreted by the press. National coverage begins Saturday at 8 PM ET on CBS.

Major League Baseball LCS Series
The animosity between the Tampa Bay Rays and the Boston Red Sox is not ready to approach the level of the Red Sox-Yankees rivalry, but their contempt for each other is a good undercard. Back on June 5th, the Rays’ Game One starter, James Shields, hit Red Sox outfielder Coco Crisp with a pitch that triggered a bench-clearing brawl between the two teams. Has this issue been resolved? Stay tuned for the answer. Meanwhile, the National League Championship series boils down to how well the Los Angeles Dodgers left-handed pitchers throw to the Philadelphia Phillies lethal left-handed hitting. The Phillies led the NL with 214 homeruns, with Ryan Howard leading the way with 48 followed by Chase Utley with 33, and both players bat left-handed. The top of the Phillies’ lineup also includes switch-hitting Jimmy Rollins and Shane Victorino, who both have outstanding on-base percentages. NLCS Game Two is Friday at 4:30 PM ET and Game Three is on Sunday at 8 PM ET; all NLCS games are on Fox. ALCS Game One is on Friday at 8:30 PM ET and Game Two is on Saturday at 8 PM ET.

New England Patriots vs. San Diego Chargers
Their franchise quarterback is out for the season, and somehow the Patriots have still put together a successful start to their 2008 season. On the other side of the field, the Chargers have been one of the biggest disappointments in the NFL. To avoid falling further back in the AFC standings, the Chargers must try to defeat a Patriots team that has eliminated them from the past two post-seasons. Inconsistent play on both sides of the ball has plagued the Chargers all season; they have lost three games by a total of 10 points. Coverage begins at 8:15 PM ET on NBC
