Well, hopefully healthy Domas is there to pick up the slack. It's weird nobody wants to give Domas credit, but dude is 18.8 PPG on 62% TS so far this year. That's about as good as a #2 scoring option as you can get. And Keegan continues to develop. And Monk gets better and better as an on-ball initiator.
It's just a silly premise in the first place, tbh. If Fox struggles, we lose. Same with every other good team in basketball; if Embiid is bad for a series they lose. If Jokic is bad, they lose. If Steph is bad, they lose. I also don't think we lose last year if Fox doesn't break his finger. Or if Domas is anywhere close to 75%, and not the 50% he probably was at after the finger/bruised sternum/black eye.
We just don't struggle to score. Pretty much ever. Like 115 points is a bad game for us. What we do massively struggle with is allowing teams to get crazy hot vs us and pop off for a huge game. We need defenders on this team where it's possible for us to win a game 115-110. Not us having to constantly drop 125+ to win.
