3 things need to happen for this to work. Chris must play faster, James must allow Chris to run the offense when both are on the floor, and James must move his feet and stay in front of his man on D. I don't like our Defense based on preseason, switching, allowing Gasol and LMA to have easy post ups aren't going to work in the playoffs.
How could that be done? I think you're missing the practicality of having one on the court at all times, and necessity of not playing all the minutes. It seems more a byproduct of a target of 34 and 32 minutes.
