Bennett is currently nothing more than an expiring contract. If seen as such, then a deal can occur. But honestly, it can't be at a high/mid first round pick, that price is too high merely on potential and an expiring contract.
Team options for rookie deals occur on Oct. 31, that means we don't have the luxury of waiting and seeing to then decide if he's worth to keep around or not, and at his price tag, high chances that the team option will be declined (doesn't mean he can't be signed as a free-agent later on, with bird rights).
But what this also means is that Bennett's value and role in all of this will merely be that of an expiring contract, which in some ways will have some value during the season, particularly at the trade deadline if anything + armed with all our picks, something can come out of it.
But I don't think it's prudent, despite of how much one would want to believe in his potential, to give up some real value for him at this point.
