Rivers puts pressure on Celtic reserves

WALTHAM — Celtics coach Doc Rivers is challenging the team’s second unit. The Celtics have started the season with a 1-2 record, the minutes of starters Kevin Garnett and Paul Pierce will not increase in a win-at-all-costs strategy in upcoming games, Rivers said Tuesday.

The Celtics host Washington Wednesday and Philadelphia Friday, then visit Milwaukee Saturday.

“No, I’m not going to let them do more,” Rivers said after practice Tuesday. “I’m going to play Kevin about the same amount of minutes.

“(Rajon) Rondo, you can go anywhere. But if we can’t win with him off the floor we just won’t win. And I told our bench that. We’re going to play the minutes that I’m giving them and the bench is going to play the minutes they should get. And they’ve got to do something or we won’t win — it will be that simple.”
