You never know. Look at the NBA. Would anyone have guessed Kobe would change his number half way through his career? How about LeBron? Randy Moss has gone from 18 to 84 to 18 to 81 back to 84 again. Tracy Porter wore number 9 at Indiana so it's not like he has a super long history with the number 22. Money talks. I wouldn't be surprised at all if Porter gives it up.
