The Boston Celtics are probably in for a rough year. But one thing they do know is that Gerald Wallace is going to outwork a lot of the opposition:

Gerald Wallace

Asked Saturday about the reasons for Boston’s inability to put together 48 consistent minutes this preseason, Gerald Wallace suggested some of his young teammates might not be familiar with the necessary level of intensity needed on the floor, dubbing the team’s effort “lackadaisical” at times this preseason.

Lackadaisical is one adjective that will rarely be associated with Wallace. Slotted in a starting role on Sunday in Montreal, Wallace injected the first unit with a jolt of energy. He finished with a team-high 16 points on 6-of-12 shooting to go along with 3 assists, 2 steals and 2 rebounds while working up a regular-season sweat over 26 minutes.

Wallace couldn’t save the Celtics from absorbing a 104-89 loss to the Minnesota Timberwolves at the Bell Centre, their sixth defeat in seven tries this preseason, but he gave another glimpse of the relentless energy and effort that he’ll bring to the team during the 2013-14 season.

Rebuilding or not, the Celtics are still worth watching.
