This is why it is so hard to repeat. The Celtics' reality is that our two best players, Tatum and Brown, are now suddenly dealing with injuries. They could be perfectly fine for the playoffs, or these injuries could linger and/or recur.
It is something all teams deal with. OKC seems the healthiest right now with Holmgren back playing although listed as day to day. Jokic is out. CLE is playing like a worn down team.
I am glad to see that Porzingis appears fresh and strong, that is good. Probably Tatum and Brown will be fine for the playoffs, but you just never know.
