I'm going to assume you aren't talking about Bonner, Blair, or Diaw.
Which means Splitter .. since Pop has done virtually nothing this season with the spurs only other 7 footer, Baynes.
Not to knock on my boy Splitter but he hasn't exactly looked like a world beater thus far in the playoffs. And he will be playing gingerly for the most part coming off the ankle sprain. Because of this .. I think the spurs will have problems and Pop will be forced to go small and this will play right into the warriors hands unfortunately. Pop will probably answer by going with his trusty security blanket, Bonner. Which will probably fail miserably. I can totally see Pop panic and send Mcgrady out there. It would really get ugly from there.
