As the Celtics  shot around at their training facility in Waltham, everyone wanted to know what the Celtics needed to do to beat King James and the Cavaliers  without last season’s defensive player of the year and the team’s heart and emotional soul in a suit for at least another week.
“He ran yesterday, he told me, on the treadmill, which I’m sure was supervised,” Rivers said . “And he said he felt great so he’s feeling a lot better. That’s the first day he’s been able to run so we’ll take it day-to-day from that point on.”
“It’s the whole knee thing. We’re just going to take our time. I would say at least a week out and most likely, longer.”
As for tonight’s battle to end all battles, at least for the next 24 hours, Rivers, possibly looking back on last year’s Game 7 of the Eastern Conference Semis, pointed out what it really means, especially if they could pull it off without Garnett, Brian Scalabrine  and Tony Allen .
“It’s a big game,” Rivers said . “Obviously, home court is at stake here. And it would be a great win for us, to beat them at their full strength and us not having Kevin, Scal and Tony, I think it would be a phenomenal win for us. We’ll be ready.”
The Celtics have allowed their last two opponents to score over 100 points while a third, Indiana scored 99 last Friday.
“We want to win, really, and we have to find a way to do that,” Rivers said . “We’ve got to improve defensively. Over the last couple of games, we have not played our defense, especially transition-wise. And if we don’t get back tonight, it’s going to be a long night. That’s what we have to improve.
“We’ve won games and we’ve lost to a couple of good teams, which I can always live with even though you never want to lose, but our defense hasn’t been consistent and for us to be a good offensive team, we have to have multiple stops and we have to get back to that.”
But maybe it was Leon Powe  who provided the best perspective of all on Friday morning, a mere nine hours before tip.
“It’s real good for us because we’ve been looking forward to this game,” Powe said of the test . “If you want to be the best you’ve got to beat the best. I know the road to the championship means you’ve got to knock us off. We see them as a real threat. We’ve got to go out there and play our best and hopefully both teams put on a good show and hopefully we come out on top.”
