Going to make a slight alteration on my initial idea:
Trade 1:https://tradenba.com/trades/jbDRsBkMHBoston trades: Daniel Theis, Enes Kanter, Romeo Langford, #30
Memphis trades: Jonas Valanciunas
Why for Boston: Significant upgrade at the C position. Valanciunas has been a beast in Memphis. 16/11 in 27MPG, leaves R Williams ~20 or so minutes as well, a significant uptick from his 13.4 this season. JV also can go with anyone strength-wise.
Why for Memphis: They shed a contract that they probably don't want to keep, as JV doesn't match the age profile of their guys. They get experienced veterans to help them stay in playoff-mode, but these guys won't get in the way of Clarke and JJJ. Also get a 1st round pick and a prospect.
Trade 2:https://tradenba.com/trades/qT68MPkrlBoston trades: Kemba Walker, #26
New Orleans trade: Jrue Holiday, Darius Miller
Why for Boston: Adds the 2nd best guard defender in the comp to the team with the best one already there! Downgrade in scoring and shooting but Jrue has more size than Kemba, can pass well and is still a decent scorer. Darius Miller could return to being a good bench shooter if his injury doesn't wreck him.
Why for New Orleans: Adds a more serious scoring threat to play alongside Lonzo, and more importantly a guy who can space the floor much more for Zion to go to work. Add another 1st rounder which could be used on a 3&D wing off the bench to replace what's lost by Miller, but younger and probably better.
Trade 3:https://tradenba.com/trades/VqzIuHtVI Boston trades: #14
Philadelphia trades: #21 and #36
Draft:21. Desmond Bane: Elite of the elite when it comes to 3P shooting, is an NBA-ready body and can play solid defence. Only concern is his wingspan, but with his shooting touch and strength I'm not overly worried.
36. Paul Reed: Defensively reminiscent of Josh Smith, except better at rebounding and less athletic (still very bouncy and long). Smith was a genuine nightmare in his day, good for 2BPG and 1.5SPG in his prime. Could always do with a defender of that calibre.
47. Sam Merrill: Insanely elite shooter, good passer, high IQ. What more could you want? His shooting is really next level, as he can shoot from the mid-range, three, both moving and stationary, both dribbling and off-ball, and is a 90% FT shooter. I think he'll be overlooked because of age, but he'll be great.
Free Agency:Say goodbye to: Semi Ojeleye, Javonte Green, Brad Wanamaker, Tacko Fall
Extend: Gordon Hayward (4/75)
Resign: Tremont Waters to another 2-way
MLE: Alec Burks
Vet Min: Marvin Williams
Roster for 2020-21:Jrue Holiday / Marcus Smart / Tremont Waters
Jaylen Brown / Desmond Bane / Sam Merrill
Gordon Hayward / Alec Burks / Darius Miller
Jayson Tatum / Grant Williams / Paul Reed
Jonas Valanciunas / Robert Williams / Marvin Williams
Given the amount of Kemba trade ideas I wasn't really too bothered giving one. I think that team is pretty near unstoppable
