Saints looked awesome--congrats.
When they went for it on fourth down, I said to my friend that I thought it was a really good call. If they converted, the game was over. It wasn't about running up the score--there simply wouldn't be enough time for the Cards to come back. Especially since they already were going to need a couple of three-and-outs.
Re: the hit on Warner. I'm undecided. I'm a hockey fan, and there are a lot of clean hits that I don't like when the other player isn't looking. Stevens hit on Lindros being the ultimate example, and something that divides a lot of fans to this day. In this case, though, I think we are all so worried about Kurt's fragility and possible retirement that it's hard not to overreact. But I also agree that it didn't have to be done. Fortunately Kurt's okay, and we'll see what happens.
