I base this on several things. This is not the first time that he has done this. When other players, just as busy as he is, makes time to see fans and old teammates, douches usually don't. He did it last year. Go watch the interview with him in the tunnel when he was leaving. Count the popped collar, backward hat, and style of dress he was wearing and yes, he looked like a douche.
I have met the man, had conversations with him and have his autograph. On this day, he looked like and was acting like a douche.
For the record, several people around me were talking about his dress and demeanor and I definitely wasn't the first to say the guy looked like a douche. That is my opinion, take it or leave it.
