Why did Miles Austin stop doing his little Celebration after a great play?

A lot of players have what you would call "signature moves" after great plays...Miles Austin had his and now all of a sudden doesn't do it anymore, he even teased the crowd once by acting like he was going to do it but laughed it off and shook his head as they started to cheer. Just wondering why he doesn't do it anymore. Thanks!|||Try to remember that you should act like you have been there before. Miles has been there before a lot. Miles is growing up.|||Probably because it's the playoffs and Dallas cant afford any penalties whatsoever especially 15 yds unsportsmanlike conduct|||Perhaps because I am Miles Austin's Great Uncle and I told him to stop it because it annoys me and I hate the Cowboys|||Probably because someone told him that looks like TO out there when he showboats. Hopefully, the kid has more class than that.|||he has a lot of class, but i suspect he is getting good enough to know that there will be many more touchdowns to celebrate, he can lay off a few of them|||Hes awesome|||Act like you have done it before. Barry Sanders used to just hand the ball to the ref when he scored.
