Sounds like he had little choice -- Boozer is first, foremost, and always out for himself. In December "out for himself" meant opting out so he could get bigger $$. With the financial problems causing teams to cut back, "out for himself" now meant using his player option to guarantee a big paycheck next season. Either way its only a one year solution, and next summmer he'll go right back to being out for himself in that ultra-crowded free agent market.
Does eliminate one way for us to speed things up aorund here though. Always a longshot, but any salary dump to free up free agent money and then sign a major player sort of strategy needs there to actually be major players available, and Boozer was about the biggest.
