I was listening to the radio this morning and there was an interview with the head ref from the championship game. He was asked about pick play in general (not specifically the play at the end of the game). I thought his response was interesting and kind of crappy.
Now, let me say first that I don't think the play at the end was a pick play so much as it was a screen play. The non-receiving WR didn't pick the defender covering the receiving receiver. Instead, hne immediately started blocking the defender covering him. If I'm not mistaken, that's a penalty (it is, at least, at either the NFL or college level as I remember the penalty being called recently). That also said, Bama shouldn't have let Clemson get that close.
But back to what the referee said. He said that for a pick play, he looks for a case where the receiver engages the defender but the defender doesn't engage back (like put his arms up). What the crap kind of rule is that?
Reminds me of this scene from Karate Kid III. You don't have to, you can just stand there and let him kick your ass.
