This is going to be a contrast in styles. However, I don't think the Lakers win this series without playing well defensively; specifically, they have to control the backboards and deny the Celtics 2nd Shot opportunities. For Boston, they need to be a bit more efficient offensively; all the advantages their stellar defense gives them is all for naught if they shoot poorly.
As a longtime Laker fan, I am looking forward to a good series. Good luck, Celtics.
