Butler did know the play was coming when they saw how everyone (including the Pats) were lined up. Butler had practiced that play over the week, making the interceptions against his practice squad.
Much like Wilson calling his TD pass to Kearse after the coin toss in the Green Bay game. They study the film, know what situations will dictate the plays, and execute. The Pats, especially Butler, excecuted the play better than the Seahawks.
It always amazes me. All I see his a bunch of big guys running around and hitting each other! (Although on the following play I was right!)
It was a phenomenal play by Butler. He travelled a fairly long distance to jump Lockette’s route. He did a great job of doing his job. 1/2 second late and Lockette catches that ball and scores.
The look on Lockette’s face as he was sitting on his butt is priceless.
