I like the randomness of the onside kick, especially since it really isn't worth a team specifically focusing on building a great onside kick recovery team. So it really does become a crapshoot at the end of the game, which I like in that situation. If they could find a way to keep the onside kick I would have much less objection to it. Think about how bad NFL officials are at calling pass interference penalties, defensive holding, etc. I think teams could exploit that on the "4th and 15" play; especially if they are a team with a savvy, top-line passing core of players. While I like the general move of the NFL to greater emphasis on passing, I'm not ready to put that advantage into the game in place of the onside kick. I think it needs much more thought. And I'm sure they will do a lot more think-tanking on it before it becomes reality. I don't think the onside kick, specifically, is the cause of injury. It's the long kickoffs with everyone flying down the field full force. One thing I agree with, looking at the plethora of articles that have come out since Goodell's comments: there's no way he would have floated the idea if it wasn't going to be seriously considered.
