I'm predicting 4-5 seed.
I'll believe in significant defensive improvements when I see it. We know this team will be able to score on anyone, but if they can't be top 50 in the country in defensive efficiency, I don't see how they can be a top 10 team. They've made strides each of the last two years after an abysmal '17-'18 season (ranked 242nd in defensive efficiency), but even last year they only ranked 97th in defensive efficiency.
A 4-5 seed would still be the best of the Fran-era and they'd have a good chance of making it to the Sweet 16. That's still a very good season.
