Exciting young QBs lead Oklahoma State, Texas into Big 12 opener

Oklahoma State quarterback Mason Rudolph was expected to be a good quarterback this season. But after failing to win the starting job out of camp, Texas redshirt freshman Jerrod Heard was a question mark.

It's a tad early to anoint Heard as Texas' savior, but he broke Vince Young's all-time record for offense in a single game against Cal. Rudolph has been efficient for Oklahoma State, but he may have to try for some more explosive plays against the Longhorns.

It's one of the best games of the light Week 4 college football schedule. ESPN breaks down everything you need to know about the Big 12 tilt.
