Im gonna take a stab that as his scoring is going up there are lots of voices whispering in his ear about the big money he is going to get. I hate when an agent gets dumped that stood by his man but the fact MIGHT be Wilson is entering a very tricky situation with the potential lock out and as the Knicks to Melo destiny moves closer Wilson needs a sign and trade more to get his bigger money than just being restricted. A well connected agent can move many pieces.
Look at Dlee. Dlee was taken care of by the knicks. He got to a premium city (San Fran when you a multimillionaire does not suck)with a great contract. He was paid last year when the team did not have to, and made sure he got his money.
I don't blame Wilson for having to look out for his career.
don't know why he has hit the wall but also opponents might have found a chink in his armor and defending him differently. Maybe a combination of lots of things.
