Mark Stein reported a few hours ago that the Sixers are after Evans as well, and Memphis wants a 1st rounder. Philly obviously has a lot higher of a pick, so they are probably not digging that idea. Unless Philly and Memphis are mutually wanting to make a deal like Luwawu&Mconnel for Evans, there isn't much else Philly can offer outside of that much higher pick then Boston will have.
We also have Yabu, who works salary-wise and Philly may want. I say either offer Larkin/Nader/2018 1st OR Yabu and and 2nd. No need to over pay for Evans. Memphis isn't going to pay him and they will be fine with taking some draft stock, young prospects in return.
Then we would still have the DPE and other moveable assets to get a higher contract expiring, and make full use of our DPE and smaller tradeable assets, while still maintaining any big chips for this off season.
I think Larkin/Nader/2018 1st to Memphis for Evans
then hit up LA and offer the DPE and a couple 2nd rounders for Randle. The Lakers aren't in a position to take on salary if they are truly trying to sign two max FA's. The DPE is the best offer, because we can send them draft assets "for free" and they still clear their cap.
Dallas is rumored to want Randle, so they could theoretically offer one of Noel/Curry/Harris, but their 1st is obviously off limits in such a trade, and I doubt they would even want to part with a high 2nd rounder to facilitate the trade.
