Probably Arrival. If you knew how your life will play out from start to finish, would you change it knowing you will never experience everything the same from the point that you change it, thus not only avoiding bad/regrettable events, but also your most cherished ones.
Is that a good deal? Green definitely has been improving and has greatly increased his 3p% this past season. Sure Klay is still good (albeit streaky) on offense, but he’s cooked on defense. That won’t work well with Luka and Kyrie not being plus defenders. Green is a hustler and at least tries on both ends of the floor.
