A possibility here:
Boston would send it's 1st round pick this year to Memphis in exchange for receiving both Davis and Ross for Pierce.
I'd like to see Bass or Terry go out with Pierce if he's traded, but it's hard to see how that would make any sense in the context of this deal.
Why would we give a 1st up in that type of deal? It would defeat the entire point of trading Pierce which would be acquiring young pieces and players to rebuild. The way I see it, Calderon and Davis don't equal a Pierce or Gay in value. The Raptors would have to include Ross(since the don't own there 2013 first) to have the deal make sense for the Cs.
If Pierce for Ross/Davis/Calderon was the offer on the table I think the Cs would really have to consider it.
Because Memphis would want more for Gay than Pierce. And because Pierce alone won't net you two prospects like Ross and Davis -- heck, I'm doubtful that including the pick would even net those two.
My point -- you'd rather have Davis or Ross than the Cs 1st this year, in all likelihood.
Memphis would want more from Toronto not from us. Memphis wants future cap relief while improving their team. They aren't going to do better than a straight up Pierce for Gay trade.
I don't really follow you -- trades are about net in and out. Memphis cares about what they get for Rudy Gay, not who gives it up.
Example: if Toronto trades Ross to Memphis instead of the Cs 2013 1st, the deal I propose likely gets less interesting to to the Cs because they have to take a lesser player from Memphis, then basically only get Davis.
Yet the Griz want more than just Pierce for Gay, notably a young player or a pick to make up for all they've had to ship out to get under the tax. If Pierce is all they'd get, then they're not likely to make such a trade.
All of this is probably moot since the most reluctant party in the deal i propose is probably Toronto. So let's say i disagree with you and leave it at that.
