I'm calling BS. He's either lying out of some false sense of embarrassment, when he shouldn't... Everyone loves him regardless, or he has the worst 17ing agent in the entire country.
You accept the training camp invite when it comes. They have far more experience and knowledge about nursing a guy back to health than TR does (he's ok with throwing to an old teammate but he won't do that under an NFL trainer's supervision?), and there is a laundry list of players signed despite an injury who were brought along as they continue to heal.
I feel for him, but that's simply not true. Not one ounce of it.
ETA: I mean, c'mon.
