It is a win for Atlanta, they have some interesting prospects at 1-4, but needed an upgrade at the five, especially on defense. Collins is shooting 35 percent from three so you should be able to play with with Capela. A big piece of Capela's value came from playing with Harden, but Trae is basically mini-Harden at this point so he should still have plenty of lobs to catch.
I'm very skeptical about Houston, it almost seems like arrogance from Morey. He is really going to push small-ball to its breaking point and I would be very concerned about asking PJ Tucker to play 40 extremely physical minutes per game.
