The PPP contract for a Trade Exception question is an interesting one. Anyone know the definitive answer? Sanders makes $3mil this season, and $11mil the next. The Pierce exception is $10.3mil, it looks like.
After a little more research, it seems like the TPE trade is a single-player only affair (plus any picks + cash that exchange hands) -- and I don't think that Sanders can be had for picks, sadly.
Well, the rule just means that the TPE cannot be combined with other (outgoing) contracts in order to match a single contract coming in.
It can still be part of a larger deal involving more players. Each team on each side is allowed to declare how they are combining the various salaries or not. The rules have to be met on each side for each team, but they are not necessarily identical groupings.
The reason each team is given that flexibility is to facilitate deals with 3 or more teams. Plus each team will have different rules governing incoming/outgoing salary matching depending on where they are relative to the salary cap.
So the TPE can be used to receive a single player making up to 10.3M (within the tolerances set by the CBA. 'Don't know the percentages off the top of my head) without having to send out any matching salary.
In _parallel_ with that, you can have an additional exchange of other players that provides compensatory value to the other team. That side deal must, of course, meet salary exchange rules on it's own for the Celtics. It can be combined with the TPE deal for the other team.
And of course, cash and picks can be tacked on to either deal to 'balance' the value.
All that said, I don't know of a Sanders deal can work or not. I have not looked into it.
