On the other hand, why waste a roster spot on a party animal who can't play and is showing no interest in learning or developing (assuming the OP thesis is correct)?
The answer for a team interested in developing a culture of winning is: you don't. It doesn't matter what his age is, or how undeveloped he is, or what school he went to, or where he was drafted. That's all sunk cost. If he has no value, he has no value and it is time to turn the page with someone that will bust his ass to make the TEAM better.
