Your Sue analogy really sucks. This was about a TEAMATE abusing him,not an apposing player. The locker room is supposed to be a family atmosphere. He didn't quit the team, the organization quit on him. If he whined that Sue hit him too hard, then I can see your point, but IMO you are way off. Nothing like keyboard tough guys!!!
You probably can't afford to quit. You don't know enough to call him mentally weak. He played at a high level at Stanford and was a high draft pick after thorough investigations from NFL personnel. If they saw a mentally weak guy, he would not have been drafted that high.Oh how I love you keyboard tough guys.
