It is the common perception that the Celtics dressing room is a healing commune where those of questionable basketball reputation can be saved. A Lourdes of leaping, if you will.

So as the Celts return home today with Terrence Williams and Jordan Crawford — two players who would not have been available to them were it not for concerns about their approach to the game and the fact they did not entirely please previous employers — there is the expectation among some, and hope among others, that regularly observing Kevin Garnett and breathing the same air will improve their focus and make them better teammates.

The newest C’s have the opportunity to either prove the perceptions a lie or rip off the old tags and begin anew.

Pierce knows that altering the career course of another adult may be quite a bit to ask, but he also recognizes it’s part of his job as captain and accomplished veteran.

“I think you just try to feel things out with new guys,” he said. “I mean, at this point in the season you usually get a chance to talk to guys in practice, but there’s not a lot of practice time.

“But it seems like these guys, from what you’ve heard about them from other teams, it doesn’t look that way from what I’ve seen in the past few days.”
