Actually what he said on Twitter during the Chiefs/Pats championship game was ""Getting money is cool, but I want a ring."

As far as negotiating mid season on the surface that does seem like a no brainer but if you stop and think about it that's a trickier issue than it appears. Lets take last season at around the game 8 point, ok so you had a horrible start but now you are on a win streak unlike any seen in franchise history. Do you really want to distract your players wit thoughts of negotiation? Also who's to say your players want to negotiate now, maybe they see the win streak and think they have a better market when F/A comes around. Or what if they feel you have low balled them, throw a hissy fit and start phoning it in, its happened before.
I don't understand why some on here are so ready to take the players at their word when they say something like this. Its easy to say "I would have stayed if they had offered" once you have already signed with another team and you're trying to make it look like you weren't just after a payday. Lets say the Texans did offer him something and for the sake of argument lets say that Mathieu was willing to listen, its not just him its his agent as well. Can you be sure his agent wouldn't, or didn't, say "Don't sit down at the table yet, you're red hot and if you sign an extension now you could miss a big check after the season."
To me Mathieu let the world know what he was all about with the things he was saying after he signed with KC. He left and showed his ass on the way out.
