I can't see any reason either team would do this trade.
There are other ways to reduce salary to get under the Luxury Tax threshold without giving away significant pieces.
Even if you feel Bass & Lee are not in the Celtic's long term plans, moving them pretty much purely for salary dump seems like a waste of their player value.
Lee actually is a reasonable piece to keep longer term. He had a down year, but he's only 27 and is a very good player and has a modest contract. I don't see the point of moving him for the sake of moving him.
I assume your purpose here is to make sure that the Celtics have the absolute worst possible roster to minimize the chance that they don't make the lottery.
But seeing Biedrins dressed in green might be too harmful to the franchise long term as so many fans would likely kill themselves after watching him.
My purpose is to eliminate some long term salary to make Boston relevant in free agency sooner. In addition, there are too many similar parts on the roster, this trims some of that out. I also think Rush, if he can stay healthy, would be a great addition and I wouldn't mind signing him long term (on a reasonable deal).
Well, signing Rush to a long term deal would probably cut the 'long term savings' here in half as he'll probably cost about 6M per to sign (He's making 4M this coming year). He's basically a slightly better offensive Courtney Lee except not as good a defender. And he's slightly older than Lee as well. And coming off a significant injury. Why not keep Lee at slightly less long term cost?
The net of that is that you are exchanging Lee for Rush and probably only clearing 4M of your long term salary.
I get the point of moving Bass, but I think you are trying to do too many things in this move.
We agree that Bass is not part of the long term picture, but he _does_ have decent player value. Probably more so as a role player for a contending team than to any rebuilding team. So I would be a little more patient and look to move him towards one of those scenarios, possibly involving a third team to make sure everyone gets the parts they need.
I don't think Rush signs a 6 million contract unless he just explodes next year. If you look around at the dollars players are being signed for, Rush isn't sniffing that. I think he could get a 3 yr, 12 million or something in that neighborhood if he is healthy and if he performs at about his career level. I just don't see much more than that. And maybe Boston just elects to let him walk and free up cap space when him, Biedrins, and Humphries go away (leaving just Rondo, Green, Wallace, and Bradley's extension as the bigger money contracts). Having that sort of flexibility is what you need as a rebuilding team, especially because unloading Bass and Lee will allow Boston to actually use the trade exception next summer.
Well, the trade exception expires July 12. Even without unloading Bass and Lee or making any other changes for that matter, they'd be able to use it between June 30 and July 12 because Bogans, Humphries, Brooks and Crawford would come off the books (assuming we wouldn't re-up Bogans or Brooks nor put a QO on Crawford). In other words, we'll definitely be able to use the 10.3M TPE no matter what.
So the only question on your deal is whether it gives us any useful outright cap room.
But replacing Lee & Bass with Biedrins' expiring and some few million of Rush is only going to net you a few million under the cap. As it stands right now, we have some 51.5M of 2014 commitments on nine players (assume we exercise options on Sully & Fab) and we'll still need to extend Bradley. Assuming AB continues as a 'starter quality SG' - then that number goes up to probably around 57.5M for 10 players. We then add cap holds for our two draft picks and the remaining roster slots and we end up quickly back in the mid-high 60s. And that's with renouncing/losing Bogans, Hump, Crawford, Brooks & Pressey. Those players have to be replaced or retained.
The maneuver you suggest (Bass+Lee+Crawford for Biedrins+Bush) gets us down into the high 50's. Probably just a few M under the probable cap. So there still won't be salary cap room to outright sign a big free agent unless we renounce Bradley.
All this suggests that it will still be better to stay _over_ the cap and instead bring in a star player via trade. And to get a larger star, the 10.3M TPE is limited because it can't be combined with other salary.
A better maneuver is to trade a package of player contracts and draft picks to get that star player because it can match a much bigger incoming contract or set of contracts.
The most flexible place to sit right now is just under the LT threshold, but with a wide variety of movable contracts and spare picks.
Danny only has to shed about 3M to get to that spot.
From there he can form almost any sort of package to match any star that becomes available via trade.
Obviously, there are lots of intermediate transactions that could happen that could transform the picture dramatically.
It will be interesting to see how Danny plays this out.
