I'd do it for Milton and picks. If we have to get on Horford's horrendous deal so be it. That means we will be less inclined to give Rudy the Supermax, which is a good thing. Supermax is a terrible idea that has killed many teams title hopeI'm glad to see there is more discussion on this topic.
For next season, I personally believe that Horford helps our team more than Conley. He makes $7.5 less than Conley as well as provides us with sorely needed depth at C and PF. He is a proven winner who can do everything at the C position (defend, shoot, pass, etc.).
Most importantly, we get assets in this deal. I would require either Thybulle or Milton PLUS draft picks.
Horford, Thybulle/Milton, #21, #58, and NY's 2021 2nd round pick
