now, i'm not in that man's head so i can't say that it wasn't a factor.

but, he just became less productive and whenever NFL backs become less productive, regardless of the name on the jersey, they become unwanted and they ultimately retire. this is coming from a Seattleite who LOVES Marshawn, thinks he should be in the NFL HOF and should (and i pray will) be in the Seahawks Ring Of Honor ASAP.

also, he's been wildly smart with his money during his career and when you do that, it's easier to retire and stop chasing the check.

also, because of the sort of character he created, partly due to how he dealt with the media, he started to get other opportunities outside of football.
