WALTHAM — Doc Rivers  knows his team hasn’t hit its stride yet.
He also realizes there’s 71 games left in the season.
But still, he, like everyone else, had to watch on Friday and Saturday as the Celtics  dropped back-to-back games somewhat unexpectedly to the Hawks at home and the Pacers on the road.
The more alarming loss was Saturday when the weary Celts allowed Indiana to shoot 53 percent from the floor and score 113 points in a loss at Conseco Fieldhouse.
“It’s nothing big,” Rivers said following Tuesday’s practice. “We’ve done a lot of things average and we’re not an average team. When you play average on defense on certain things, and offense, you lose. It’s more of that. It’s nothing earth-shattering. It’s nothing we’re going to panic about. We know we have to get better.
‘To me, the way we’ve played so far, we’ve been a spurt team. We’re not ready yet to be a 48-minute basketball team, that’s just not what we’ve done yet. We’re working on it.’
Meanwhile, one of the Celtics best defenders of the last two seasons ‘ when healthy ‘ has been Tony Allen . The guard has been out with a right ankle injury since off-season surgery but could be getting closer to returning as he is now practicing with the team.
‘He did well actually,” Rivers said. “He moved and played great. He’s moving well. I’m not sure if he’s ready to play yet, honestly. I just don’t know yet because I do think he’s not sure of his injuries. There’s several times he’ll jump and you can see he’s clearly thinking about it and I don’t like putting players on the floor when they’re thinking about it because that leads to something else.’
