You've got to guard Monta like you have to guard Arenas, JR Smith, etc. because they will literally pull up for ANY look they see.
When you've got Monta Ellis falling out of bounds on the baseline 20 feet from the basket and he's actually taking the shot you can't give him an inch for the rest of the game.
EDIT: Down the stretch we had Bradley on Curry and Rondo on Monta.
