Typically a league that loses one Heisman Trophy-winning quarterback and another that threw 37 touchdown passes is going to see its overall passing numbers slip.
There's nothing typical about the Big 12.
The departure of Baylor's Robert Griffin III and Oklahoma State's Brandon Weeden for starting jobs in the NFL has done nothing to limit the league's preposterously successful passing games.
Four of the nation's top five quarterbacks in passing efficiency play for Big 12 schools, led by West Virginia's Geno Smith and Texas' David Ash.
Oklahoma State's J.W. Walsh and TCU's Casey Pachall are fourth and fifth respectively in efficiency, and Smith and Baylor's Nick Florence rank first and second in passing yards per game.
There are only 10 teams left in the Big 12 - and yet eight of them are throwing for over 200 yards a game.
"It's a tad bit scary, to tell you the truth, because of the volume of points that are being scored," Kansas coach Charlie Weis said. "Every week you look at the scoreboard and you say 'My gosh.' "
Folks around the Big 12 are still having trouble comprehending what Smith did in West Virginia's first game as a member of the league.
Smith's 656-yard, eight touchdown performance in a 70-63 win over Baylor will go down as one of the most transcendent passing performances in the history of the game. Smith and the Mountaineers seem to be a perfect fit for the Big 12, and they've certainly caught the attention of Texas coach Mack Brown ahead of Saturday's matchup with the Longhorns in Austin.
"They're just unbelievable," Brown said of Smith and the Mountaineers. "He just makes no mistakes. He's very confident. He's very smart. The receivers are unbelievable."
Smith isn't doing it alone, of course. West Virginia receivers Tavon Austin and Stedman Bailey are second and third in the nation in receptions per game and, along with Smith, were unstoppable in September.
"The rapport that they have with Geno is going a long ways. They've been hanging out together for going on four years," West Virginia coach Dana Holgerson said.
Ash, a sophomore, spent much of last season sharing duties with Case McCoy. He has come into his own so far in 2012.
Ash has thrown 10 touchdown passes while completing 78 percent of his passes. He was outstanding in last week's 41-36 win at Oklahoma State, with 303 yards and three TD passes.
