It's nice to hear them speak that way. You learn more from losses than from victories, and this team will have the chance to learn a lot this season.
I don't know if it's lack of effort, chemistry, growing pains or lack of urgency. I'd say it's the latter, and I don't think it's a bad thing if you think about Coach Stevens "process" approach. They're learning together, coach included, so you can expect them to lose a lot. Danny is a genius, this team will be in the lottery while trying as hard as they can. I'm convinced they'll play their best basketball in March/April, as an irrefutable proof of the "we're not tanking" theory.
By the way, don't be like Sherrod, don't get fooled by the Tank Ninjas of Philadelphia. Once the Regular Season starts, they're going to enter Tank Commander mode. Celtics won't stand a chance against them for the worst record. Maybe Orlando...
