KA Towns is exactly the type of player that the Celtics would reach to add in my opinion. A young big with huge. What more can you ask. He could easily start alongside Horford and then with 3 of Irving, Brown, Hayward, Tatum (assuming one of them get traded), that is a great young team.
The problem is that I don't think the Celtics would trade either Irving or Hayward so that would mean giving up either Brown or Tatum. Also, Minny already has Butler and Wiggins so don't really have a slot for either of them. I PG makes the most sense for them but I don't see Irving going there.
Bottom line, nice thought but can't see it matching up.
