A closer look at one statistic worth keeping an eye on for each Big 12 team entering Week 5:

Baylor: Don't forget about Antwan Goodley. The potential All-America receiver went down with an injury in the season opener and enters Big 12 play with zero receptions. While KD Cannon and the rest of Baylor's wideouts feasted in his absence, Goodley is back this week, and he and Bryce Petty have some catching up to do. No Big 12 player matched his 598 yards after the catch last season.

Iowa State: Well, the Cyclones are 2-0 in home games against Baylor under coach Paul Rhoads. During the Art Briles era, Baylor has averaged 33.2 points per game on the road against the rest of the Big 12. In their losses in Ames in 2009 and 2012, Baylor's offense put up a combined 31 points. But ever since that 35-21 loss at ISU in 2012, the Bears are 19-3.

Kansas: Tony Pierson has recorded 280 touches on offense in his career at Kansas. He's gained 10 or more yards on 25 percent of his touches and picked up 20-plus yards on 26 of those 70 plays. The majority of his big plays have come on rushes, but Pierson is also averaging 12.7 yards per reception in his four seasons. He's instant offense, plain and simple.

Kansas State: ESPN Stats & Info analyzed the Auburn-Kansas State game tape and determined Jake Waters was pressured on nine plays. He completed three passes, threw two incompletions and an interception and took three sacks. K-State's net yardage when the Tigers got pressure on Waters? Just 15 yards. Waters and his linemen will have to handle the heat a bit better in Big 12 play.

Oklahoma: How will freshman Samaje Perine follow up his 242-yard night at West Virginia? In the past decade, 19 FBS running backs have surpassed 240 rushing yards multiple times in a season. If Perine does it again this year, he'll join some elite company that includes Reggie Bush, Matt Forte, Le'Veon Bell, Ray Rice, Jonathan Stewart, DeAngelo Williams, Andre Williams and, yes, Adrian Peterson.

Oklahoma State: The Cowboys rank No. 2 nationally in a statistic that's pretty darn important: red zone efficiency defense. OSU's defense has entered the red zone 10 times this season and permitted just two touchdowns. Opposing offenses have had to settle for field goals seven times (one was blocked) and Jameis Winston threw a red zone interception. Getting stingy under pressure like that will pay off big in Big 12 play.

TCU: The Horned Frogs are one of only two teams in FBS that have played just two games entering Week 5. (Cincinnati started the season bizarrely with back-to-back byes.) This isn't just some silly observation. The fact is, starting this week against SMU, Gary Patterson's team must play eight games in eight consecutive weeks before getting a pre-Thanksgiving reprieve. They face a brutal run in October (OU, at Baylor, OSU, Texas Tech) and need some gas in the tank if they hope to make a run in November.

Texas: It's hard to believe that, with Malcolm Brown and Johnathan Gray both healthy and splitting time, Texas ranks No. 9 in the Big 12 in rushing right now at 123.7 yards per game. That's 99 fewer yards per game than Oklahoma is averaging and almost 115 fewer than Baylor. The culprit here is a shoddy offensive line, but the downhill run game was supposed to be the strength of the Longhorns' offense and they've struggled without one.

Texas Tech: One not-unreasonable excuse for Texas Tech's problems on defense: According to its sports information office, 17 of 27 Red Raiders who've recorded tackles this season are freshmen, sophomores or newcomers. That number does include Kenny Williams, who moved from running back to linebacker this spring. The rest are young guys who better catch up quickly.

West Virginia: Clint Trickett ranks No. 3 nationally now with 1600 passing yards, a feat through four games that most WVU fans probably wouldn't have predicted back in the spring. He leads all Big 12 passers with 20 completions of 20-plus yards (nine to Kevin White), but then again, Trickett also has 43 more completions than any other quarterback in the conference. Let's wait a few more weeks before assessing where he fits in the Big 12 QB hierarchy, but this is a heck of a start.
