If this is to try to take down the Warriors, then I don't think its well conceived. It seems to be an attempt to match up against them. Their 4 is better, and their cap scenario would be better.
I think the most likely way to beat them is by being faster at guard and bigger up front, not trying to match up. Our current roster gives them problems because our guards are difficult for their guards. There isn't much we can do with Durant however, and Green would not get overpowered by Horford.
We would need to add a physically aggressive small forward and an imposing big combined with Bradley, IT and a better bench. Give Jaylen Brown 2 years and 15 lbs and he might be the small forward to give Durant a problem. Perhaps getting Griffin and keeping Bradley is the answer to the puzzle.
