NBA Player's Performance Enhancing Behavior: Chewing Straws?

NBA superstar and Dallas Maverick's player Caron Butler has an addiction. Actually he has two of them.  For his most recent addiction, the NBA has now gone on to ban this behavior during games due to safety concerns.  What is it you ask?  Has to be something performance enhancing or drug related right? Actually, the NBA has banned Butler for chewing straws during the game, of which he goes through at least 12 a game--60 per day!  Talk about quite an oral fixation.  This got me thinking, why does he do this?  There's obviously a reason for this behavior.  Well Butler stated in his blog that this habit calmed him down, especially helpful during NBA games I imagine.  His motivation for this behavior was to satisfy his physiological response of stress and anxiousness.  Arguably, this was a performance enhancer of sorts for him.  It'll be interesting to see how much the extinction of this behavior will affect him.  Looking back, this behavior could possibly be correlated/as a consequence of his first habit:

In summer 2009, Butler blogged on NBA.com that he had lost 11 pounds just by giving up his daily "addiction" of drinking at least six 12-ounce bottles of Mountain Dew.

"I was going through withdrawals," Butler said on NBA.com. "... Honestly, those first two weeks without The Dew [were] the roughest two weeks of my life. I'm talking headaches, sweats and everything."

Like the straws became a psychological need and fixation, Butler had conditioned his body to the physiological extremes with his habitual caffeine intake.  It had really become an addiction. 

It will be interesting to see how Butler's behavior will be affected by the NBA's banning of chewing straws during games.  Will he take up another habit to help calm him down?  We'll see.  Here's a link to a video clip and article discussing the situation.  It's funny to watch the video and see all the fans and radio broadcasters who came to the game chewing straws in support of Butler's behavior.  It's also interesting to note in the sportsnation poll that 54% of people in America enjoyed chewing on straws...:
