Hard to see a healthy Miami squad missing the playoffs. Everybody else seems up for grabs.
It's easy to look at the Celtics and think they lack star power and they just got lucky last year, but they aren't a team based on a lot of highs and lows. Their defense is top notch - especially at the guard and wing positions. They also have a roster closer to resembling Stevens' style of play - everybody knows their place and the players really seem to buy into his system. Finally, the roster really did perform well once the trade deadline passed (2nd best behind Cavs, blah blah blah).
Listen, I agree that it's hard to get behind this team as an upper-tier threat and pre-season rankings will probably place the team in the 9-11 range, but I wouldn't be surprised to see them finish as high as 5th in the conference, with a couple of players making a mini-leap. I also believe this isn't the roster we will see come opening day - there will have to be some kind-of consolidation of players.
Overall, nice post LB - you laid out very well what needed to be said given the underwhelming draft and FA signings.
