LMA sucked before the bubble for a while and doesn't fit well with the team or, frankly, the league. Extremely hesitant to adapt his game and just shoot 3s like the team needed. Years of clamoring for his "touches". To me, that's enough of a sample size.
As for DMDM, most of the same still applies, but at least he showed (along with the team) some marked improvement. I'm not saying it's proof of anything longterm but it shouldn't be discounted completely. Yes, there were many other factors in the bubble: no Forbes and the young players actually got some run.
So: If we can trade LMA, then it seems like a no brainer. If we can trade DMDR also, then I'm ok with that too.
