Boston in 6. Lakers in 7.
The only time the Lakers have been down significantly at any point in any of the games was when PHO shot 72% in that 41 point 2nd quarter in Game 4. They've been down no less than one point (I believe) heading into the 4th of every game.
But most importantly, they haven't lost an elimination game at home with a championship caliber team since Jordan's first title in 1991.
I will say the team that plays the hardest will win. That is what has happened every game so far.
