Because sometimes jammed up plays in your favor. The design of the play is that the lead receiver picks the two defenders leaving the second receiver open for the TD. Which apparently the Pats understood and practiced against that play, so Butler knew he had to take a different line and not get picked. But if the Pats don’t spot Seattle’s fondness for that play in tape review, and Butler doesn’t read it properly pre-snap and adjust the way he’d been taught, there’s a little pocket of peace right there for the receiver and TD Seahawks.
You can try to explain away the stupid call all you want. The majority of the football watching (and coaching and playing) universe all agree that it was a stupid call. Add to that it was to Ricardo Lockette. With the Super Bowl game on the line do you go to one of your superstars? No, you go to a guy who had 11 receptions this year and has 18 receptions for his career. But I guess that was another way to fool the Patriots, right? Go to the guy who is least likely to get it in that situation.
