Here's a look at this week's collection of who's hot and not around the Big 12.
Sizzling -- Oklahoma redshirt freshman WR Ryan Broyles and redshirt freshman LB Travis Lewis. Broyles produced OU freshman-record marks of 7 receptions and 141 yards in his first game last week. And Lewis has emerged as the Sooners' starter at weakside linebacker, leading them with 18 tackles and two sacks.
Hot -- Baylor's rush defense, which permitted only 52 rushing yards against Northwestern State.
Not -- Iowa State's rushing defense, which is allowing an average of 211.5 yards per game and permitted nine runs of at least 10 yards last week against Kent State.
Hot -- Colorado KR/WR Josh Smith, who is averaging 19.6 yards every time he touches the ball and has produced four returns of 40 yards or more.
Not -- Colorado KR/WR Josh Smith, who has fumbled in each of the Buffaloes' first two games.
Hot -- Iowa State's opportunistic defense, which has already produced 10 turnovers this season. The Cyclones had 18 turnovers in the entire 2008 season.
Not -- Iowa State tailbacks, who produced only 55 yards on 28 carries, an average of 1.96 yards per carry, last week against Kent State.
Hot -- Texas QB Colt McCoy, who's averaging 6.5 yards per carry this season.
Not -- Texas' running backs, who are collectively averaging 4.4 yards per carry this season.
Hot -- Kansas QB Todd Reesing, who has a four-game winning streak in true road games heading into Friday's game at South Florida and a seven-game streak of 200-yard passing games.
Not -- Kansas TB Jocques Crawford, who has produced 29 yards on his last 16 carries. Crawford bragged about rushing for 2,000 yards before this season. After two games, he's only 1,951 yards short.
Hot -- Missouri's offense, which scored five touchdowns last week in only nine minutes of game action against Southeast Missouri State and is the nation's only unit ranked in the top 19 in both rushing and passing.
Not -- Missouri's defense, which has allowed six scoring drives of at least 56 yards in the first two weeks of the season and ranks 115th in pass defense.
Frigid -- Texas A&M's running game, which is averaging only 112.5 per game and 3.0 yards per carry, both last in the conference. Yes, it's the same unit that features backs like Michael Goodson, Jorvorskie Lane, Bradley Stephens and Cyrus Gray.
How much have the Aggies struggled running the ball recently? A&M generated nine runs of 7 yards or more on their first four possessions of the season (in the first half against Arkansas State). But since then, A&M has produced only six runs of 7 yards or more over their last 20 possessions.
