If it's a draft night deal, it's got to involve Pierce or Rondo. There's no other way to make the salaries match up.
won't we have a bunch of cap space so we won't have to match salaries ?
That cap space doesn't arrive until July 1. Draft is June 28.
I'm fairly certain that you could agree to a deal in principle and execute it once our players are renounced. Which would mean the Hornets would be selecting for the C's and we would later acquire the rights to that said draft pick.
That is true. It's why I prefaced my comment with "if it's a draft night deal."
But, more importantly, why would the Celtics renounce free agents to bring in Ariza, if Pierce is also on the roster?
Edit: Unless the plan is to blow the roster completely up, so you've got Rondo, Bradley, Ariza, JJJ, Moore, three incoming rookies, and cap space to try to land free agents.
