I just don't know why it's so important to some people to continue to hold up Jayson Tatum as this wonderful player despite how much the team has struggled as the team has increasingly become centered around him the last couple of seasons. It's possible to appreciate Tatum without insisting that he has no flaws and all the team's problems are due to everybody but him.
Who is saying that? If anything people are critical of Tatum, they just disagree with your assertions in this thread.
I appreciate Tatum. I am happy to build the team around him. To be a top 5 player though, there are areas he will need to improve. Ball movement, getting to the foul line, getting inside vs. settling for jump shots. Complaining to the refs (did I miss anything?).
I also think the team around him has holes, the schemes they try to run as a team are not well executed by the entire team (making it tough on him when doubled), coaching is not great so far under Udoka, and injuries and illnesses have prevented continuity of playing time for the core starting line up. Smart, Brown, Tatum, Horford, Williams have only been on the court together for 16 of 51 games and 194 total minutes. For perspective, Utah's top line up has 30 games and 481 total minutes together.
Tatum has had some headwinds this year. The team has not been great. The coaching has not been great. There has been a lot of missed time. Tatum has played bad at time on his own as well. Tatum is a star though.
