I think House is probably the better option, but Cedric Maxwell disagrees with me. He says House will have the ball taken from him. I disagree that Fisher and Jordan Farmar could do that. Maybe PP could play point forward or something.
Brick James disagrees with you too. House will have the ball taken from him, as he has proven throughout the season.
This is precisely why Ray Allen brought the ball up the floor, even with Kobe on him, when House was in the game against Farmar.
This led JVG to say that he'd like to see a backcourt of Allen/Pierce with Posey at the 3.
A Lakers fan wants Eddie in there - that should be enough evidence that Cassell belongs there first.

It's Cassell's spot to shoot himself out of.
