As someone who had the Saints in my pick'em pool last week, I loved the call. There are times to go for it on 4th down, even deep in your own territory. That wasn't one of them. It's too easy for defenses to sell out to stop a run on a do or die play. I don't know if it's always been this way, but it seems like no one can punch in a run at the goalline with any consistency, that was basically the same idea. Now had they called a play-action with a TE sneaking out, that woulda been ballsy, and probably wide open.
Punt the ball, play defense and get it back, those guys get paid too. They stopped the Saints on O a number of times during the game, do it again. But like I said, it worked for me!
