re: Watson: "We we worked on that Pick All Year" ... And it was perfectly legal

Defending a pick play is exactly like defending a screen. It's all about reading the signs of the setup, and reacting before the offense draws you in. In the case of the pick, you have to beat the screening WR to the spot. Adams blew up 2 in the Ole Miss game this year, because he read it (it was pretty he obvious he had seen it in film study the way he reacted) ahead of time and jumped the right route before he could be blocked. As mentioned before, you can also defend it with a switch, but most straight man teams will struggle to do that if they haven't seen the play before.
