there may be an overall improvement in CJ's efficiency if the new coach forces CJ to stop going one-on-one so much and significantly ramps up CJ's catch-&-shoot and spot-up opportunities while dramatically cutting his iso and dribbling. I can't see a new coach changing CJ's stripes though. CJ has averaged a high volume of shots from one-on-one (and one-on-three) for 12 years....that includes 4 years at Lehigh. He's also not going to increase his FT rate
the real problem is what standard is used to set the value of a 'good return' for CJ, and how much the Blazers would have to add. Expecting an all-star back is loopy...won't happen. But in this forum, as long as people keep talking about CJ's all-star talent (in the East!!), it's going to be difficult to discuss realistic trade ideas.
and, as mentioned, any CJ trade idea needs to leverage the possibility of Powell stepping into the starting SG role. I guess that could be similar to trading Zach Randolph in order to open up the PF role for Aldridge. Or the Warriors trading Monta Ellis to open the spot for Klay. In other words, there could be more benefits to the trade than just what's coming back
I don't believe for a second a new coach is going to be able to scheme this Dame/CJ team into a contender. And as long as CJ is there, hogging an all-star's level of shots and usage, and also hogging an all-star's level of the salary cap, there's no room, or means, to add the singular talent that would make for a contender and not waste what's left of Dame's prime
