Danny Ainge doesn’t know if the Celtics are good enough in 2020 (Tim Bradbury/Getty Images)

Last year the Celtics were very good on paper. Chemistry flushed their season down the toilet. Now we think the Celtics chemistry should be fine this season. What we don’t know is their talent level. Swapping out Kyrie Irving for Kemba Walker is a downgrade on paper. So is swapping Al Horford for Enes Kanter. Danny Ainge is concerned the Celtics don’t have enough talent to compete in 2020.

“I think that last year’s questions were more based on how is it going to jell? There was not a question of how much talent we had,” Ainge said to reporters before today’s open practice. “This year, the question is, are we good enough? And can players step up and take advantage of the opportunities that they’re given to become more elite?”

I already covered this in my season preview but I think the Celtics have a wide range of outcomes this year. Do Jaylen Brown and Jayson Tatum progress or remain the same? How much better can Kemba Walker get with Brad Stevens and a better supporting cast? How much will the Celtics miss Al Horford? How does Enes Kanter make them better or worse? How do 3 rookies (Maybe 5) factor into this roster? Which Gordon Hayward are we even getting? There are so many questions that need to be answered with this team.

The only thing I know is that Tacko Fall needs to make the roster. I will not rest until that’s the case. He’s a gamechanger in his 10 minute window he can contribute. With a roster in need of bigs, Fall fits right in. If he doesn’t make the roster, I’m going to be very upset. Do the right thing, Danny. Keep Tacko Fall.
