I'm not sure where the excessive confidence about the bench comes from.
Smart is a nice defensive role player, but is unreliable at best offensively. Terry Rozier has yet to really play much or produce at the NBA level. Jaylen Brown is a raw teenager. Gerald Green is an itchy-trigger-finger shooter who shot below 33% from deep last year. Jonas Jerebko is a solid jack-of-all-trades combo forward, an acceptable plug-in who doesn't do anything especially well. Kelly Olynyk is a useful and versatile PF/C with range, but he will still be recovering from shoulder surgery for the first part of the season. Tyler Zeller is a matchup-dependent backup center.
The talent on the bench is remarkable. But there are a lot of question marks.
Our bench is one of the best in the league. IMO only GSW has a clearly superior bench.
As a Celtics fan your opinion is super biased.
After losing Turner we can only assume our bench got worse.
That is unless your factoring in production from unproven players like Rozier and Brown and improvement from Smart.
CBS must have a whole squad of Celtics fans writing on the NBA for them.

I've read this a day ago. Looks more like a Utah fan to me
And in any case, it is far from the best piece of online sports journalism.
Back to the point, our bench is pretty good. Certainly above average, and arguably top-5. Smart, Rozier, Green, Olynyk, Jerebko and Zeller is nothing to scoff at as a second unit - and then you have this year's rookies - no one knows how much they will be able to help, but if a couple of them prove serviceable, then our bench will look even better.
Depth is not our problem. Far from it.
