I think Martin flipped out because of the pressure and he got bent about being pushed at times by his teammates in order to get him to improve. I think he ran home, and for a few weeks listened to his mommy, and then before he realized it, his mothers legal advice had dug him a huge hole. Now he's trying to crawl his ass out of it and save whatever is left of his career.
"Thanks mom"
I think in the end, this is going to be more of a case of a young adult not having the maturity to handle adversity and then listening to his whackadoodle lib mother whose immediate thought was how to set up a payday. By the time Martin realized that wasn't really what HE wanted, it was too late.
Trade him to Frisco for a 5th and be done with it. Frisco will go for it, he can be a solid backup with his college coach, nearby to home....and they have a crapload of extra picks again anyway, a 5th is practically a throwaway.
