Yeah, the two big off season acquisitions failed us in game 2. Holiday wasn't very good, Porzingis was worse. He played worse than you would expect from Kornet. I still think that you have to make the trade of Smart for Porzingis. We barely have enough size as it is. We would be severely limited if we had another guard instead of Porzingis.
The discussion on Holiday vs. Smart is different. It is a hypothetical to debate if we would be better off with Smart over Holiday, while still having Porzingis, as that scenario didn't happen. It wasn't a real option. It almost was, but it wasn't. It isn't a real trade that you can consider undoing. I have been saying all season that Holiday has not been much better than Brogdon was last season (that is a real trade you can debate undoing). That isn't to say Holiday has been bad. He has been solid. But how much have we really benefited from that trade? I would say only a little, and most of that is due to Brogdon's injuries.
I suspect that both these guys bounce back and have good games in MIA. I know it sounds crazy, but I would consider starting Horford and bringing Porzingis off the bench. Just for one game. Just to throw a curveball at MIA. Still keep the same rotations in general, but just flip the script a little at the start of the game (Horford defends the perimeter much better). Hopefully jump out to a lead, force MIA to call that first Time Out, then put Porzingis right in to negate any adjustment they would try to put in.
