A closer look at one statistic worth keeping an eye on for each Big 12 team entering Week 8:

Baylor: When it comes to the big-play passing game, Bryce Petty is as good as it gets: His 11 touchdowns on passes thrown 20 yards or longer leads the nation. He scored six of those against TCU. A total of 30 of his 48 career passing touchdowns have come on those 20-plus yard throws.

Iowa State: The Cyclone can make a case that they've played one of the toughest schedules this season. Their six opponents thus far have a combined winning percentage of 83.3 percent, highest in the nation. The first five teams they faced -- North Dakota State, Kansas State, Iowa, Baylor and Oklahoma State -- are now a combined 26-3.

Kansas: Michael Cummings' 288 passing yards against Oklahoma State were the most by a Kansas quarterback since Dayne Crist threw for 303 in a loss to TCU on Sept. 15, 2012. That means Kansas has now gone 27 games since its last 300-yard passer. Cummings could be the guy to snap that streak soon.

Kansas State: You know a Bill Snyder-coached team is going to be disciplined. This group is upholding that reputation: K-State's 20 penalties and 162 penalty yards on the season are fewest among all Power 5 conference teams. Its underrated defense has only accounted for four of those mistakes.

Oklahoma: Against Texas, the Sooners became the nation's first team in two years to win despite a -250 yardage margin. The last time a Big 12 team pulled that off was 2004, when Colorado beat Washington State despite being outgained by 277 yards. The last time we've seen anything close to that in a Big 12 game was Kansas State's 41-34 win over Texas Tech in 2011 (-241 yards).

Oklahoma State: Give Kansas a little credit. Oklahoma State finished with 275 yards of total offense on Saturday, their fewest in a game since the 2010 Cotton Bowl. In fact, OSU snapped its 57-game streak of at least 300 total yards, a run that had ranked second-longest nationally behind Oregon (59).

TCU: A few of the more impressive gains when you compare TCU's offense through five games to TCU's first five games of 2013: The Horned Frogs' total offense is up 188.6 yards per game, scoring is up 17.8 points per game and passing is up 132 yards per game. It helps that TCU has run 100 more plays through five games than at this point last season.

Texas: One of the more impressive aspects of Texas' play on defense: its effectiveness in the first half of games. Texas' defense has been responsible for allowing just 12 points in the first half this season and is holding foes to 57.8 first-half passing yards (No. 2 in FBS in that category) and 54.7 rushing yards.

Texas Tech: It's been a rough run for the Red Raiders, but one area they don't get enough credit for: They're keeping Davis Webb clean. Webb has been sacked only two times this season and Tech's offensive line has given up five sacks, allowing them on 1.7 percent of their snaps. That rate ranks No. 3 nationally. Freshman Patrick Mahomes took the other three sacks.

West Virginia: Baylor's comeback against TCU was incredible, but West Virginia's rally in Lubbock was nearly just as improbable. According to ESPN Stats & Info's win probability data, the Mountaineers' odds of victory with 7:32 left in the fourth quarter (after giving up a Justin Stockton 69-yard touchdown run) was only 4.2 percent.
