I don't like the Love component but I'd absolutely acquire Harden.
I still am not sold trading Walker is the right move, however when you acquire Harden, the optics aren't as bad.
I think I'd do something like this
Boston - Harden, Gordon, Randle
Houston - Brown, Knox, 2 BOS 1st
New York - Walker, Theis
Boston post-trade
Starters - Harden, Gordon, Tatum, Randle, Thompson
Main Rotation - Teague, Smart, Langford, Nesmith, Williams, Williams
I think that team has more top end potential thus giving it a better shot at winning the title. And it does work without Gordon, he just struck me like a player that Houston might want to move on from if they moved on from Harden. I might include Smart if I had to (it also works that way) though would fight to keep at least one, if not both, of the picks in that scenario.
