WALTHAM -- Carlos Arroyo's first practice was a short, open session in front of a handful of season ticket holders at Health Point, a slightly different setting from the media-frenzied hype machine he had gotten used to in Miami.
"It was just to much at times," Arroyo said. "Media everywhere, fans everywhere. It was a lot. It was a lot, like people say, like being the Beatles, . But I’m happy to be here."
With just 21 games left to pick up the Celtics's schemes, Arroyo said one things were familiar if only because of Arroyo's past battles with the Celtics.
"He played against us in two playoff series," Celtics coach Doc Rivers said. "So he knows some of our stuff."
Arroyo will eat some of Rajon Rondo's minutes. The Celtics' all star point guard is averaging more than 39 minutes a night since January. Arroyo will be the first true backup point guard the Celtics have had in a long while.
"He’s a point guard," Rivers said. 'He’s been a point guard all his life. So I think some of the stuff, he’ll pick up pretty quickly. And all the nuances of things, that’ll just take time. But he knows how to run a team and that’ll be great for us."
