I am always hoping that my team has none or very few players that knowingly are of character so questionable that it makes it hard for me to cheer for them.
Thus I prefer to say no to guys like AP, Joe Mixon, and I am more than a little torn on Michael Floyd (though lots of his Notre Dame teammates insist he is a good guy with a treatable issue and a desire to beat it).
I don't expect them all to be choir boys, and things like pot possession bother me a lot less than crimes like beating women, beating kids, theft, gun violence, or driving high/stoned/drunk.
I have to admit it can be a sliding scale though. I don't look to athletes as role models and i want them to freakin' play well, and hard.
