There is no way the Colts could have scored twice within the small ammount of time that they had available to them, even IF they had the ball. So the Saints taking that knee was really just them being respectful to the Colts in my opinion. In stead of continuing to beat a dead horse, they just ended the game.
But personally I wanted the Saints to win, yes I am technically jumping on that band wagon, but I previously had no other team that I cared about (I didn't start following Football until last season) And the fact that my Dad has been a Saints fan since he was a kid, he's from Mississippi, that all made it easy to pick them up as my team... Along with the fact they were a raping machine...
