I would like Doc to try KG and Luke, and Glen Davis with Semih...that way you have a rookie on the floor with a veteran. I know that KG doesn't like to play center and doesn't really play with his back to the basket, but both Glen and Harangody are pretty effective shooters from 18 feet in and both have a pretty good nose for rebounds. If Shaq cant go we might as well try something different and still give KG a little breather, and not wear Davis out either (especially with the way he keeps sacrificing his body.
I know Doc doesn't like to play rookies, and Harangody might not get any minutes, but I would like to see if he can keep his composure in a "big game" situation. Luke, like Davis, brings effort and hasn't seemed to get overwhelmed or flustered easily. This would be a big test...if he fails you have at least gotten someone a few minutes break, if he succeeds, something more important has been learned.
