Points for consistency in the face of facts that don't support your position. 
I actually agree with you -- it's the Josh Gordon conundrum, but if you can't put down the bong long enough to keep your job, the fault ultimately lies with you. I don't think there's anything wrong with Sanders that a change of scenery won't fix, while you're convinced he's the next coming of Vin Baker. the truth, probably, lies somewhere in the middle.
He's repeatedly risked his $11m per year job to smoke pot. He literally said, at the time of his suspension, "I believe in marijuana". And your conclusion is:
a. Larry Sanders takes his career seriously
b. A change of scenery will solve this problem
I don't even know what to say. I have to agree to disagree.
I'm not sure if this is a reading comprehension problem (I've repeatedly said and agreed with posts that Sanders smokes too much for his own good) or something deeper, but let's review the steps you've taken in this thread:
He doesn't like playing basketball. This is kinda' important.
Sanders is a simple case. He doesn't like basketball. End of story. I don't want him.
There was a related quote where Sanders said (to paraphrase), "I like basketball, but I don't take it as seriously as some people".
What agent in his right mind wouldn't immediately deny such a report? Larry's own words and actions agree with the narrative that he's not that interested in his basketball career. I don't trust agents, ever.
I don't want him on the Celtics, he doesn't take his basketball career seriously, and I don't trust his agent. I'm not wavering. All those things are true.
He's been suspended multiple times for not taking it seriously (violating league policy). I don't need a confession. He's guilty as charged. He's about to be bought out for this very reason.
And maybe we should sticky this, so future CelticsBlog posters know exactly what "shifting the goal posts" looks like. You don't like Larry Sanders. Fine. Whatever. But you're continually operating as if your position is entrenched in anything close to the zipcode of fact, when it is not -- just a judgement call and inference based on a thin slice of criteria.
That doesn't mean that you're not right, but it does mean that you could very easily be incorrect.
