Every time it seems Rajon Rondo has reached his peak, he manages to climb to a new summit. Celtics coach Doc Rivers believes Rondo has finally reached the rarefied air of great players because the 26-year-old point guard is finally delivering consistently.

Rondo always has been capable of posting a historic stat line, but he was just as likely to follow it with a lackluster effort that left everyone, including Rivers, scratching their heads. But not in this postseason, and certainly not in the Eastern Conference finals.

Rondo had 15 points, 15 assists and five rebounds while playing 47:05 in the Celtics’ 93-91 overtime win over the Miami Heat in Game 4 last night at the Garden. That such a line has become routine is the true mark of Rondo’s progress.

“He’s good. That’s what he is now when you think about it,” Rivers said. “He’s just a good basketball player — great basketball player. And now he’s consistent. That’s when you cross the line, when you’re no longer inconsistent.”
