The Boston Celtics jump up to No. 6 in the ESPN.com NBA Power Rankings this week.

Here’s what our Marc Stein had to say:

"In the midst of a 9-1 surge, with the offense humming, Celtics radio play-by-play ace Sean Grande paid us a visit Sunday night on the NBA Insiders show on ESPN Radio and pointed out that Boston not only ranks sixth in the league in nightly point differential (at plus-4.3), but also sports a top-six record in the whole league since the last Super Bowl."
