I know it's fun to laugh at Kansas, but that is absolutely 100% the QBs fault. Hell, I'd even say that's a nice job by most if not all of the linemen. The d-line all have their hands down fending off the cut when the qb should have thrown the ball.
Either the QB ran the wrong play or the Line did, and I find it hard to believe all 5 linemen heard the wrong protection.
