Probably has no ride for some reason. Either it is true he was demanding way more money than the market was going to pay (this was reported all over the place), or there is attitude issues (this was reported too), or people did not want to deal with Big James. I agree, hard to believe a guy gets #1 and cant find someone to give him a shot.
I tend to believe #1, that he demanded way too much cash. This is the one thing that seemed to come up the most on different sites. You can only get what the market will pay. So perhaps it is his fault he did not get a ride.
