Yeah, with just a bit of analysis into this I don't think we can swing anything cute on the TPE front. But I don't know that we solved MIA's problem for them.
First, since we're sending out Mo and Meyers, it's an aggregated trade. Because neither one could get Whiteside by himself salarywise (and they barely do aggregated), it's a simultaneous trade (125% of outgoing salary +100k).
Now, before the trade with us, MIA had to send out 26.08M to PHI to complete the trade. Richardson is only 10.1, so they had to find a way to send out at least another 16M. They'd been looking to move Dragic, but that stalled out. Enter us. They get Leonard and Hark, but can't trade either within two months.
So technically, I guess they could "have a deal in place" and execute it September 7 where they send Meyers and Mo with Richardson for Jimmy, but PHI doesn't want to take on 22M they don't have to for the privilege of giving up Butler.
There's a realm where this becomes a 4-teamer (with someone like DAL using cap space) but that gets really messy.
Guess it's just a straight-up, ho-hum trade.
Butler's salary starts (if you believe the 4/141M number) at 32.7M. Richardson (10.1) , Whiteside (27.1), Meyers (11.0), Hark (11.3) are others involved
