The Boston Celtics will have a few days off before they host the Dallas Mavericks on Sunday at TD Garden. But after back-to-back wins on Tuesday and Wednesday against the Philadelphia 76ers and Toronto Raptors, the Celtics currently have the best record in the Eastern Conference at 10-2.

I will admit that, so far, I've been wrong in my early season prediction of the Celtics. After trading Jaylen Brown to the 76ers, I had the Celtics pegged for a fifth or sixth seed in the conference. And right now, they appear headed for a top seed and potential homecourt advantage in the Eastern Conference playoffs.

So where exactly did I go wrong through 12 games?

I believed that George could be a good player for Boston. That was never really a doubt. But after playing 60 games or less in six of the last seven seasons, I simply felt that George wouldn't be healthy or available enough to make a big enough difference to vault the Celtics to a top seed.

So far, he's been excellent. In 10 games played, he's averaging 22.0 ppg and 5.2 rebounds. He has missed two games, so the team is cognizant of his minutes, but he's been so good when he's played that the group has been able to pile up wins.

It's the depth. George has missed two games. Jayson Tatum has sat out a game for load management, and so has Mitchell Robinson, and yet, the Celtics just keep on ticking. Derrick White, Sam Hauser, Robinson, Neemias Queta and Payton Pritchard have all had big games to help this team earn wins.

The depth was something that I frankly overlooked. In the regular season, when other teams are sitting stars, the Celtics have the advantage most nights. They have a higher volume of good players than many teams do and that's shown through in the season's first month.

In fact, Colin Cowherd of FOX Sports Radio highlighted the depth and the strength of the bench on his show on Wednesday.

Well, depth won't matter as much in the playoffs, so can the Celtics beat a team full of healthy stars in a seven-game series? That's the question.

They are racking up wins in the regular season against a generally soft schedule and some teams who have guys out because of rest or injury (Kawhi Leonard on Wednesday). What happens in a series when depth isn't the big thing, and star power is?
