Xs and O’s

Times staff writer Lonnie White breaks down the keys to Game 4 and looks forward to Game 5:

Three keys from Game 4

No panic: Veteran-led Celtics maintain composure and rally from 24-point deficit to take commanding 3-1 edge in the Finals.

L.O. fade: Lakers’ Lamar Odom has a dominant start but doesn’t contribute much in the fourth quarter.

Ironman effort: Boston’s Ray Allen never leaves the game and makes several clutch plays down the stretch.

Three keys to Sunday’s Game 5

Defense, please: After holding Boston to 14 first-quarter points, the Lakers give up 83 over the final three periods in Game 4.

Too many threes: Brick-shooting Lakers miss 15 of 21 attempts from beyond the arc.

Doc Rivers: Boston’s underappreciated coach has to continue to push the right buttons with his matchups against the Lakers.
