Former UMaine Black Bears and now Dallas Mavs coach saw his team take a 30 point lead on the Boston Celtics, only to see it slip away and almost blow the whole thing.

The Mavs did hold on in the final seconds to win 118-113.

Chandler Parsons scored 29 for Dallas. Jeff Green pumped in 35 for the C's. Avery Bradley scored a career high 32 but missed a free throw that would have tied the game with just seconds to go.

The Celtics fall to 1-2. The Mavs are 3-1.

NOTE: The Celtics return home to take on the Toronto Raptors Wednesday night. Sports Radio 92.9 The Ticket will carry that game live with coverage starting at 7pm.
