Colin WAS a good quarterback, time ago.  Above all, professional sports loves winners.  They'll put up with all kinds of inconvenience if their teams wins.  When he started losing, his playing time decreased.  When his extracurricular/political antics became a distraction, nobody wanted to sign him.

jjfoxy's commentary is just as legitimate as your own.  Calling the person "cowardly" was entirely inappropriate.  If you can't bother to be civil, then shut up.
