In response to a couple things:
1) True, big stiff have always occurred, even before Shaq. The difference is that there are now more of them. Furthermore, a lot of them were drafted with Shaq in mind. I can still remember on the night Diop was drafted we (and the media) were talking about how he had the size and strength to stay with Shaq.
2) As far s Scalabine being a tough guard for Shaq, that's absolutely true. And that's why big stiffs don't work against Shaq. All they do is give him a license to sit under the basket. This is exactly how the C's beat the Sixers in 2001 or 2002 with Rodney Rodgers at center. Mutombo either had to drift out to guard Rodney, opening up the middle or if he didn't, Rodney hit wide open threes.
Thus, I see no reason why we can't use the same game plan we've been using (Scal) against Phoenix.
