Back room deal:
The Raptors want to move Solomon and need a big to replace Oneal on the bench at the 5 spot.
Sacramento wants salary cap relief and cash.
Boston wants Moore.
But due to the salaries involved and the restrictions in how much money can be included in a deal and how much money each team could afford. A strict trade wouldn't work. But if there is a pretense of trades for second round picks and cash and Sacramento promises to but out Moore to some predetermined number so that the Celtics could sign him and Moore's agent is down with the whole thing with a little wink and nod, then the whole deal goes down the way it does and Danny, due to the wink and nod, has to sign Moore. If he doesn't, Moore's agent comes forward with the tampering and the Celtics pay big time ala Minnesota/Joe Smith.
The way it worked everyone save a little money and got the players they wanted. I mean think about it, who the hell puts protection on second round draft picks to the point of making them impossible to get? No one, that's who. It was all pretense to make it appear legal.
