The Boston Celtics are reconstructing themselves, and there are bound to be some growing pains in the process. Here’s NESN reporting:

Gerald Wallace

Wins do wonders to smooth frayed nerves.

A couple of hours after expressing exasperation with his role and frustration with being taken out of the starting lineup, Gerald Wallace changed his tune after the Celtics recorded their first win of the season with a 97-87 victory over the Utah Jazz on Wednesday. The 13-year veteran even joked a little about his 31-year-old body’s adjustment to the rigors of coming off the bench.

“My back tightened up coming in there,” Wallace said. “It’s a lot different coming off the bench, but other than that, it was a fun experience for me.”

Wallace scored nine points — his second-highest scoring total of the season — in 23 minutes as a reserve as the Celtics hung on after letting their 25-point lead get whittled down to six points in the fourth quarter.
