There were moments when it looked like the glorious run of the New Big Three might be over.

Not yet. There’s at least one more round of playoffs for the Old Bones of Causeway Street. In a series that could have been sponsored by John Deere or Black & Decker, the Celtics defeated the Philadelphia 76ers, 85-75, in Game 7 of the Eastern Conference semifinals at the Garden on Saturday night. Boston’s Wheez Kids live to play another day. Time to bring on LeBron James and the Miami Heat, starting Monday night at AmericanAirlines Arena.
