Many players pick numbers because they wore it in high school or it's the number of their favorite player. Some are forced to change because of veterans or retired numbers.
I already knew a lot of them, but there was some cool insight that I did not know on some.
Some that they didn't list that came to mind:
-Arenas switching to #6 for "six shooter" after his gun incident. Then switching to #9 after the NBA found out the reason for picking #6.
-Metta wearing 37 for # of weeks Michael Jackson's Thriller was #1
-Artest wearing #23 & 91 for Jordan & Rodman
-Artest wearing #93 and 96 because it spelled "QB" for Queensbridge in their respective fonts
