To me that is just code for "I'm taking the highest offer in free agency."
Right.
He knows his play was sub-par, and that he stole money on his contract. But this has never happened to him before, and he's likely to blame it on being in the wrong place at the wrong time. He's tired of reading about being a huge disappointment, and he's eying a fresh start to get back on track.
The only type of player that would come back to all the negativity is one who has absolute loyalty to the owner, team, city, and fans; a guy who is 100% confident that he can and will excel in this system, and is dedicated to repaying the investment in him. I don't think that's where Mo's head is.
He'll be looking to reboot.
