Who's hot and who's not in the Big 12

Posted by ESPN.com's Tim Griffin

Here's a look at a few numbers and statistical trends that struck me while poring over media sheets in preparing for this weekend's games.

Sizzling: Big 12 quarterbacks. Nine of the NCAA's top 25 quarterbacks come from Big 12 teams heading into this week's action.

The number: 497. That's the number of yards needed by Graham Harrell to pass Kliff Kingsbury and become Texas Tech's all-time leading passer. Harrell has 11,933 yards, Kingsbury produced 12,429 yards in his career.

Three of the top four career leaders in FBS career touchdown passes will have a connection with the Big 12 on Saturday.
Here's a look at the players and who they will play on Saturday

Note: Massaschusetts QB Liam Coen has thrown 75 TD passes to lead all FCS quarterbacks heading into Saturday's game against Texas Tech.

Hot and Not

Hot: Baylor, whose 28-point victory over Washington State was its largest over a BCS opponent since beating Iowa State in 1996.

Not: Iowa State, which moved the ball inside the Iowa 30-yard line six times but produced only a field goal offensively.

Hot: Missouri's defense, which has run back an interception for a touchdown in four straight games.

Not: Kansas' defense, which allowed 31 unanswered points in South Florida's 37-34 victory last week.

Hot: Oklahoma State's defense, which limited Missouri State to 1-for-17 third-down conversions.

Not: Oklahoma State WR Dez Bryant, who followed up his nine-reception, 236-yard, three-TD effort against Houston by dropping the only pass thrown to him against Missouri State.

Hot: Texas Tech's offense, which has scored at least 30 points in 19 of its last 21 games, including seven games in a row.

Not: Massachusetts, which has lost nine straight games against FBS teams since beating Ball State in the 1984 opener. The Minutemen's coach for that game was current UTEP athletic director and former Missouri coach Bob Stull.

Hot: Kansas, which has won 16 straight home games against nonconference opponents heading into Saturday's game against Sam Houston State.

Not: Sam Houston State, which has been outscored 165-27 in the last three games against Big 12 teams.

Hot: Missouri QB Chase Daniel, who has directed 13 straight scoring drives.

Not: Nebraska's secondary, which struggled with three pass interference calls last week.

Hot: Missouri's receiving corps, which posted three 100-yard receiving games against Nevada. Jeremy Maclin (172 yards), Chase Coffman (127) and Tommy Saunders (100) all reached the standard against the Wolf Pack.

Not: Iowa State, which has lost 11 straight games on the road heading into Saturday's game at UNLV.

Frigid: Texas' pass rush, which had produced fewer than two sacks in eight of its last 13 games.
