I had seen that on TV Tuesday morning...a fun play, similar to one a year or two back where the quarterback said this is the wrong ball and walked to the sideline to exchange it before he sprinted to the end zone.
When I was at Lehigh, our team was pretty bad one year, but pulled a trick play where the quarterback bent down to tie his shoe, and when the defense relaxed we ran a wildcat type play pretty successfully, against our arch-rival Lafayette.
