Who needs Dame or CJ when you have Anfernee Simons???
Without being funny, I think trading all of our older players, going for 1-year tank and then rebuilding with Simons, Little and whatever we can get for CJ, Dame etc. is the way to go, absolutely. This current team is not fun at all at its best, and having a refresh is what we should hope for.
E.g. let's trade Dame for Simmons, Maxey and 2 first round picks. Trade Nurkic to Charlotte for one of their young players (PJ Washington would be ideal). Trade CJ to Cleveland for Sexton, Rubio and a pick. Trade Nance and Covington for whatever you can get, you will probably get a late first for Nance and a pair of seconds for Covington. Maybe get something for Powell too.
Then in a year your team may look like Simmons, Maxey, Simons, Little, PJ Washington, Sexton, one of the high lottery picks etc, and that's actually a proper playoffs team in a year or two + you don't need to pay ageing players a fortune.
EMBRACE THE TANK.
