UFAs Tristan Thompson, Jordan Clarkson and Jeff Green.
Veterans who can really play and immediately contribute. Thompson and Clarkson are still young. Tristan could really help in rebounding, defense and inside scoring. This holds true in Green's case plus he remains a very good 3-and-D guy which he did very well in Houston. Clarkson at 6'4" runs plays well, full of confidence on his shot (inside and out), very quick, hustles, knows how to pass in open court and even in heavy traffic inside, can penetrate and has respectable one on one offensive game.
They could really instantly help coming from the bench.
