While the TCU offense ran the ball with ease (238 yards, 160 from Anderson), the Horned Frogs defense made life difficult for Heisman candidate QB Mason Rudolph all afternoon.

But instead of letting Rudolph or stud running back Justice Hill do the work, OSU dialed up a trick play — a wide receiver pass with Jalen McClesky.

So instead of potentially cutting the lead to one possession with five-plus minutes left, the Cowboys gave it back to TCU with a two-score edge.

Oklahoma State cruised past Tulsa, South Alabama and Pittsburgh in its first three games but weren’t quite ready for the physicality of TCU.

Oklahoma State opened the second half with the ball, but Rudolph threw an interception on a screen pass on a great play by TCU’s Chris Bradley.
