I think I would make that deal.
Tucker, gordon and capela for tpe and boston 2020 first, protected.
Capela is one of the few centers whose defense can cover hayward or tatum playing as a pf
Gordon and tucker are further trade assets for all i care. Are not really long term solutions anywhere.
Smart/edwards/waters
Brown/gordon/langford
Tatum/tucker/semi
Hayward/williams/yabusele
Capela/williams/room mle
Tucker is non guaranteed in 2020 and gordon is expiring. So they could fetch a nice asset by deadline, or could be flipped after 3 months to a team in need for assets.
I do that deal all day.
