Celtics:
Marcus Smart: will be interesting to see him without an ankle injury and with a full year of experience under his belt, plus he'll start from day one. I'm pumped for him.
Crowder: He will be the starting 3 on purpose for the whole season, I want to see how he develops from here. There is a scenario where he plays really well, it would be cool to see that.
KO: I want to see him embarrassing other teams' benches early on and get a taste for it. He absolutely has it in him, but he needs to beat up on bad players to get going.
Non Celtics:
Porzingis & Hezonja: I want both of them to be good, because I want world basketball to be better than it is and these two would be hugely influential if they pan out. It feels dirty and gross to root for a Knick, but I'd love to see Porzingis succeed in particular.
Greg Monroe: The whole Bucks team is interesting, but I don't remember a signing like this before. I would love for him to do good
