BOSTON — Well, the old man ain’t done yet. Derek Fisher scored 11 of his 16 points in the fourth quarter and shadowed Ray Allen into 0-for-13 shooting in Game 3 of the NBA Finals tonight. Fisher’s coast-to-coast layup and free throw after he was hacked sealed the deal for the Lakers, who lead the best-of-7 series, 2-1. Fisher made 5 of 7 shots in the fourth quarter. Fisher will be a free agent July 1 and will be 36 when training camps open in the fall. He said he has no plans to retirement and hopes to remain a Laker for life.
