Wilson was a back up, if Flynn would have shown anything remotely better than he did, Wilson would still be the back up, and Seattle would be 8-8 and fans screaming for his head to be amputated. Carroll would be a horrible coach, and the owner be called the worst, because he won't fire and get a real coach / GM.
The draft is a lot of luck at times. Especially in the later rounds. Good coaching can help those type players though. This is where I think Dallas needs to make coaching changes, in some assistants.
As for the X-games, I'm glad you mentioned that. First, he had to be at the combine, it's his job.
JJ's title may carry GM, but when he was at the X-games, it was Garrett interviewing coaches at the combine not the GM....
