Kansas State moved the ball pretty well in the first half, but only put seven points due to two missed field goals and an interception in the endzone. But according to Bill Snyder the offense could have been better if Auburn hadn't figured out the Wildcats' signals. ESPN's Sam Ponder discussed the issue before the start of the second half.
Auburn was accused of this against Arkansas earlier this year and against Florida State in last year's national title game. Stealing signs is just part of football. It's up to teams to do a better job disguising them.
