Nothing I can't stand more than those "oh, poor little millionaire" type posts. I sympathize with his plight, but players should be aware of how it comes off.
That said, I think there are likely just as many, maybe more, players who left a good situation and bolted for the big contract, and really regretted it. Hindsight is 20/20. I really don't know enough about his career to know how much he left on the table. If he can still play, he'll get a shot somewhere and might be able to still cash in if he proves himself.
