its a wonder you even waste time with this, they are professional athletes and emotions run high....ur kidding right?
Listen to your self....Professional athletes don't start fights and get ejected before the opening kick offs...to me their is nothing professional about that move.....if anything it shows a player without much upstairs. Its good to get fired up for your opponents but you channel that emotion into the game with legal plays and hits that don't cost your team in the over all scheme. Ejections and costly penalities because of emotions out of control is not smart play nor is it playing like a professional athlete. The ejection before the browns game was the only instance I'm aware of that Porters watched from the locker room but last year he showed a habit of similar tendencies with refs having to stand between him and opposing players during warm ups. If I'm in Camerons shoes those are the things I'd want to eliminate with Porter.
It was my opinion when the thread starter asked for concerns about porter and If I were the head coach those would be my concerns. You sign a player with the idea he will add to your teams quality and depth and seeing him ejected with out playing a single down is not what the organization brought him in for.
