I hated the Rozier pick at the time, but I've grown to really like it since watching his highlights, summer league, and pre-season. However, I will withhold on how I feel until I see all three play against legit NBA competition because we still have yet to see that.
Overall I like the young guys the Celtics have brought in, but the one issue is the Celtics aren't going to keep all of them. I seriously wonder if Smart, Hunter, Rozier, Young, Bradley, Sullinger, Olynyk, Zeller, Mickey are all going to be here 2 years from now. It's not that any of them are bad. I think they will all be good players, but the only guys I see as top notch players on the team going forward are Smart and possibly Rozier (Feel free to disagree). Again no knock on any of those guys, but the Celtics have an ocean of valuable picks and they need their centerpiece players. When the centerpiece gets here, the Celtics will have to open up some roster space to make room for them. Whether we like it or not, some of our young guys are going to be traded.
