Boston is at a critical point this summer. It needs to really pick a direction and do some drastic things.
To be clear, I don't think this will happen, but I do believe in a vacuum the trades are at least fairly reasonable. And I don't know that this will make Boston a contender, but I do think it would set the team up better in the future. There are plenty of possibly variations of this of course.
Trade 1
Boston - Love, Sexton
New York - Walker
Cleveland - Knox, Langford, Edwards, NY 21 1st
Trade 2
Boston - Morris, DEN 21 1st
Denver - Smart
Trade 3
Boston - Kuzma
Los Angeles - Thompson, G. Williams
Re-sign Fournier
New Roster excluding draft picks and free agents or Semi or Kornet (4 open roster spots)
PG - Sexton, Morris, Pritchard
SG - Brown, Fournier
SF - Tatum, Nesmith
PF - Love, Kuzma, Parker
C - R. Williams
Obviously team needs more center help, but I think this team is set up better long term and probably functions a bit better on the court next year as well. You take on Love to get Sexton, but Love can still play when he is actually healthy enough to. I think having a look at Sexton and adding a solid 4th option type in Kuzma makes a lot of sense. Morris is a credible guard and you get another 1st (plus shaves some money) in the trade.
