I don't think you send Kemba out, especially for someone like Love because then there is a giant gaping hole in the backcourt.
But this would be why I'd want someone like Zeller from Charlotte. He would get you more than halfway to acquiring Love.
Maybe make it a 3-Team trade
Charlotte - Hayward, Edwards, 2021 BOS 2nd
Boston - Love
Cleveland - Zeller, Theis, Green
I think Boston would be below the apron and could do that, but if needed a bit extra salary could be included.
I'd feel much better about Boston's chances of actually competing in the East with this roster
Guards - Walker, Smart, Teague, Langford, Pritchard
Wings - Brown, Tatum, Ojeleye, Nesmith
Bigs - Love, Thompson, Williams, Williams
2 open roster spots with Fall and Waters as 2way (maybe you give Madar a contract or maybe you just bring some vets in at some point)
