Why replace the best player you have on the team? Why not find a Center to help this team?
So you can rebuild around a better player?
You're talking about rebuilding exclusively through free agency? Trying to do the Knicks and Heat thing? If the Heat get themselves another defensive center on top of current bigs Bosh, J. Anthony and Haslem, as well as better PG than they've got now, then Chris Paul plus our original big 3 is not going to get it done......
If you're going to trade Rondo in order to rebuild, you should trade him for multiple young or reasonably young players and picks, preferably a pick in the 2012 draft. Plus, if you're looking for a PG with a jump shot, don't give up the great Rondo and all he brings, as well as a bunch of rebuilding tools, to get a slightly better version offensively. Instead, get a lesser PG but with a
better jump shot than Paul, a guy who plays good defense and doesn't turn it over, but who lets Ray, Paul and KG keep their strong imprint on the team. Something along the lines of Rondo and Bradley for Teague, Heinrich and a 2012 first rounder.
