He isn't wrong though. The team is worse than last year's team.
On paper yeah, probably.
If "on paper" was all that mattered, then last year's Celtics probably would have won the East, and the Raptors would have been demolished by the Warriors.
Fact is the Celtics have made the ECF with less talented teams then this, and with the departure of Kawhi (Raptors), Butler and Reddick (Sixers) and Brogdon (Bucks) you could make an argument that the other top teams in the East have all taken a backward step as well, in terms of pure on-paper talent.
Boston seems to be the only one of those teams that has potentially made a major upgrade to it's intangibles as a result of it's roster changes.
I think the Bucks are going to be excellent. They lost Brogdon, but they were without him for much of last season and were still dominant - I expect them to remain dominant.
The Pacers added Brogdon so I think they are going to be better - a backcourt of Brogdon and Oladipo (if they can stay healthy) will be one of the best in the league. They could be a surprise team.
The Raptors have dropped off in a huge way and I'd be shocked if they finish anywhere above 5.
The Sixers gained Horford but i really don't know how he is going to fit alongside Embiid. Horford is at his best when teams are playing through his as an interior playmaker, and I just don't see him getting a lot of touches on a team that already has Simmons, Embiid and Tobias Harris. The Sixers may well run in tot he same type of chemistry issues Boston had last year. Throw in the loss of Reddick (critical for their spacing) and Butler (critical as their closer) and you have what I see as a bit of a mess on Philly. I don't think they are going to be as good as they look on paper. I also question their coaching.
I don't see Boston having a better record then Milwaukee, but I think they are plenty capable of finishing anywhere in the #2 - #5 range.
