I’m a bad Celtics fan, having jumped on the bandwagon sometime during the Cleveland series, but the heart displayed by this Celtics team is impressive. Former Celtic great and sometime color man Bob Cousy often says during games, “the C’s have got to increase their defensive intensity.” Defense is all about heart and the display of it by this team and its leader, Paul Pierce, is admirable. If the Lakers have any hope to get back in this Series starting tonight, it’ll be on the defensive end of the floor where they’ll do it. Personally, I don’t think they have the heart.
