After the first 7, the Celtics have a G League roster. But I blame Danny for not finding some veteran minimum guys to fill out the rotation. You've got the 5 starters + Smart. You can't really trust anyone after that in a big game. Kanter can contribute offensively, but kills you defensively. The rest can defend but can't score at all.
To me it's unconscionable that Ainge couldn't find them some help. They're going to hope that their top 6 and the longer breaks between games in the playoffs will be enough to get them through. I'm guessing it won't.
