Also, trading for a guy like Porter would only have an effect on the cap in the 3rd year assuming we gave them some combination of Leonard, Turner, or Harkless (if he could pass a damn physical).
Does getting Porter get them closer to contending?
I think it makes them better this year but not over the top unless GS completely implodes (keep in mind they will most likely still be adding Cousins to the mix later on this year). So you would have neutral salary impact for two years and then a big cap hit for one year in 2020-2021 for what likely will amount to a slight to moderate tick up in the playoffs but definitely not a title contender still. One thing to keep in mind is that Dame, CJ, and Porter would all be on the same contract length so in the summer of 2021 they could just decide to tear it all down like in 2015 with a new owner, GM, and coach.
