How has a team full of "nice guys" worked our for us the last decade or so?
I want some nasty, and not "run over a chick" nasty, but a "ima use your couch for a nap cuz I can" nasty.
Honestly, talent really is the only thing that matters on the field, but if they can't play nice off the field and it impedes their playing time then yes, there's a problem. Right now, though, we're dealing with "what if's".
