[Hammock Parties]

Ted Johnson is another example.

Johnson, 34, suffers from such severe depression that some mornings he literally cannot pull himself out of bed. When the crippling malaise overtakes him, he lies in a darkened room, unwilling to communicate with his closest family members.

The 10-year NFL veteran believes his current state is a direct result of a career in which he absorbed "countless" head injuries, including back-to-back concussions suffered within days during the 2002 season, when he says the Patriots didn't give him proper time to recover.

The Patriots' medical staff ruled Johnson out for the remainder of the game. When he arrived at the stadium four days later, he said, he expected to find a red jersey, signifying minimal contact, in his locker. Instead, a blue jersey -- signifying full contact -- was dangling from a hanger.

"I grabbed Jim Whalen right away," Johnson said. "I asked him, 'Is this right? Should I be wearing a blue jersey?' Jim immediately said, 'No, no, that's wrong. You are not cleared for contact.' "

Johnson pulled on the red jersey and took the field for stretching and individual skills. Shortly before the team was about to engage in their 9-on-7 drill, which is one of their more physical exercises, Johnson said an assistant trainer hurried up to him and handed him a blue jersey.

"I looked at the trainer and said, 'Who told you to give me this?' " Johnson said. "He just walked away. He didn't want to say. But I knew who it was. It was Bill [Belichick]. I was so mad I wanted to scream. But I put the damn thing on anyway. I had my pride. They weren't going to beat me."
