I said before the playoffs that I thought this team was better equipped for a deep post-season run than last year's team.
It doesn't mean they will get as far, or further. The are elite defensively, both as a team and in individual one-on-one matchups. Baynes is better than Johnson, Morris than Olynyk, Brown than Bradley, Tatum than Crowder, Rozier than Thomas. Even Ojeleye and Moose provide some unique defensive help. As a team, they no only can matchup defensively, but right now, they are mostly on a string with each other, responding to each other's rotations. Last year's team had that, but they didn't have the ability to stop offensive players one-on-one.
Offensively, last year's team with Thomas on the court was really, really special. They were not as good with him off the court. However, the Cs have more players this year that can create shots than last year's team. Last year, it was mainly only Thomas -- everything else was part of the motion of the offense. This year, Tatum, Brown, and Morris can all break down their man. Horford has been a better shot creator in this year's playoffs too. On top of that, Rozier is providing like 80% of Thomas' production, shot creation, and offensive power.
I still don't know how deep this team will go, but evaluating them on their talent and togetherness, I'd say they have a better chance to make a deep playoff run than last year's team.
