I mentioned this last year that the elephant in the room in Horford’s age and decline as our long term contender status.
That's why we need to trade him this summer to get Davis.
The Celtics are not winning a championship the upcoming years unless they bring in another (super)star. You can't win it all with only one All Star. And it would be foolish to just wait till Tatum and Brown may reach that level. So we have to make a big trade soon (probably in the summer), since now we still have valuable expendable assets.
Anthony Davis is a recurring name, but it doesn't seem likely that another star comes available who's a long-term solution and a good fit for the team. Maybe a small chance that Towns would want out of Minnesota? Gamble on Porzingis or Sabonis, although unlikely that the respective franchises would want to part with either. Or do we go for a less appealing name in Nurkic or Vucevic with the hope that they will sustain the level of their career year?
