Legler: 'Celtics a work in progress'

Tim Legler says the Celtics have a rough road ahead and will need to improve their defense and step up their offense if they expect to keep up with Western Conference titans like the Spurs (Wednesday, 7:30 ET) and Thunder (Friday, 7:30 ET).

"Right now the Celtics are a little bit in disarray offensively," says Legler, who adds that Jason Terry "hasn't found his niche and role yet, and I don't think they're utilizing him to the extent that they need to when you consider the fact that he's replacing Ray Allen."

Legler calls the Celtics "a work in progress," and notes that Doc Rivers has built the team to peak in April, May and June. "That's certainly what they're worried about," he says.

As for this week, Legler says, "I think Doc Rivers more than anything wants to see his team buckle down defensively against these two teams."
