I can somewhat understand when a guy like Sean Taylor, who probably got a signing bonus in the range of $7 million, have that attitude of superiority about them. Heck, they don't even have to play well and they'll be a multi-millionaire.
But Peppi Zellner? This guy is barely even an NFL-caliber player, and he is compelled to skip voluntary workouts? Why do teams even give scrubs like him so many chances? He's never recorded more than 3 sacks in a season, and the Cardinals will put up with it?
