Some of the trades won't be straight up, but there all gonna be two team trades and there all gonna be simple.
Bucks: Yes, they are giving up A 2029 FRP which is questionable, but, it's protected. They are also saving 4.4 million, which when you look at the lottery penalties comes up to at least 10 million dollars in saved money (including the 4.4 million they'd save if they did this). DFS would fit well because of his defense and would make them better.
NETS: They are probably not trying to win now, therefore getting a frp for someone is good even if its late. Allen will be gone in a year anyways so the money isnt too big of a deal.
