Since the last time Oklahoma State played Baylor, the Cowboys have played four different QB's.

Brandon Weeden, their starter last season, is now in the NFL while freshman J.W. Walsh and A.J. Lunt have been struck down by injuries, leaving third-string junior QB Clint Chelf in charge of coach Mike Gundy's high-powered spread offense.

However, no matter whose behind center, Oklahoma State has been putting up points, and a lot of them at that, on the scoreboard. The Cowboys come into Saturday's game in Waco with the No. 3 rated offense in the country, scoring an average of 45.6 points per game.

Chelf, a lightly regarded 6'1 205 junior, has compiled typically gaudy statistics in his four starts this season: throwing for 1,058 yards, 10 TD's and 4 INT's while completing 58% of his passes.

It will be a huge test for a Baylor defense that has found its footing in recent weeks with victories over Kansas State and Texas Tech. A win would push their record to 7-5 on the season, enshrining the Bears place as a mid-tier Big 12 program, an almost incomprehensible leap from where the program was when Art Briles took over in 2008.
