TRADE: JRich to BOS | $10.8M TPE + Moses Brown (7'1.25", 7'4.75" wingspan) to DAL

[F Gump]

We have enough room now that I'm not sure there's a way to operate over the cap in a KP for Lowry deal unless 1) Lowry is making the most he possibly can in that trade (i.e., eating into our cap room) and other pieces like Kleber, Powell, et al. are outgoing for bigger salary as well. 

If we traded KP for SnT Lowry, I would rather not offer Lowry more than 3/90 (in which case we still have $33M in cap room), clear more cap room, and go after Holmes. I'd also rather Norm Powell than THJ in that scenario, but a man can't be too greedy.

Lowry
Powell
Luka
DFS
Holmes

If we could get Ball instead of Lowry, then Ball-Powell-Holmes would be close to being my ideal offseason.

I'm not sure I follow what you're saying .... if you're saying those ideas don't work in preserving over-cap status, and enabling the Mavs to keep their TPE plus also room to re-sign THJ, you're wrong. And I'm looking at a 3/90 deal.

If you're saying that after a trade like that, you might prefer to work as an under-cap team, that's true. There would be choices, depending on who you traded for Lowry, and who else you see as a desirable and realistic target(s).

An aside about your players you lust for, I suspect Powell will be way more expensive than THJ. THJ's salary may start a bit less than we think. And I also think Holmes will get way less than people here are projecting - too few teams with cap room, plus he's a center which depresses what he is likely to be offered. Paying more than $15M would be an awful overpay (bidding against yourself, I suspect) in the market.
