Is a Ray Allen Post-Season Sign-and-Trade Possible?

[LooseCannon]

With the shrinking salary cap and the glut of high-profile free agents, Ray Allen is part of that veteran middle class that is likely to find themselves forced to be underpaid for the MLE.

I'm pessimistic about being able to get good value for Ray Allen in a mid-season trade.  In fact, if Allen were traded, I would want it to be a waving of the white flag that gets Ainge a draft pick or two to work with. 

Another option is gambling that you can package him in a sign-and-trade after the season with a team that expects to lose a free agent and wants something of value in return.  I'm not a salary cap guru, but I believe after the season Glen Davis is no longer a base-year compensation guy, which makes it easier to trade him.

What would Big Baby at $3.3 million and/or Rasheed Wallace at 6.3, with Ray Allen signed to something between $8 and 12 million get?  I suppose there are a lot of players who would do it in a heartbeat if it could net Dwyane Wade with a contract extension.  Who else is worth it?  What are the chances of it happening if Ray doesn't get traded before the deadline?

I think it will be much harder to trade Ray in a sign and trade than it is prior to the deadline. His primary value is his expiring contract, not his talent, that's what makes him a poor sign and trade candidate.

The idea I had, just to make everyone retch, was that Washington might want to get rid of Gilbert Arenas and find it can't void his contract, so decides to try and trade him and found Ray Allen to be an upstanding citizen who could anchor the team while they rebuild.  That's a fantasyland scenario, but really I'm just wondering if there are any big names likely to command big contracts who are sure to bolt teams that would prefer to get something instead of nothing.

But I just wanted to know if, in general, such a sign-and-trade of some sort is a Plan B if there is no deadline trade that nets sufficient talent to be worth doing.

Most contract offers will be in the MLE range, so there is little the C's can hope to gain in a sign and trade scenario.
