I really think Holiday is the difference maker for them. How many games did he make a key play down the stretch to either swing the game their way or seal the deal. If Porzingis is back it will be interesting to see if they start him. I don't know if they want to mess with this dynamic they have with Horford right now. As long as Horford is playing well, I think they roll with him. If he goes 1-7 from 3 in game 1 and Porzingis is looking healthy and good then maybe they make the switch.
