I don't think so, even if Tatum returns close to his pre-injury form
I don't think JT will return close to his top form this season, particularly in terms of chemistry. But if he does and this team gels, I think our upside is as high as any team in the league, including OKC.
People forget that last year against the Knicks that we got nothing from KP and Jrue and JB were injured. This year's squad is better than what we showed in the playoffs.
This is true. It seemed like the team was gutted when we lost Porzingis, then Holiday, then Horford; some were even bemoaning losing Kornet, but it turns out, losing them was not as bad as it seemed. Now with Vucevic in the Horford role, once we get Tatum back, I see this team as right there with anyone, certainly in the East. Some other teams have gotten better, others got worse, it is still kind of TBD where BOS will be when/if Tatum returns.
I am not worried about chemistry but I am worried about Tatum. He is going to have to make adjustments, not because of new team roles, but trying to regain his form on the fly. Once the competitive juices start flowing, he is going to revert to doing what he used to be able to do. And he may not be able to right away. It may take time. And that may mess with his confidence. He may also be perfectly fine, pick right up where he left off after a short break-in period.
The team/players will welcome Tatum back, I have no doubt of that.
