Care to expand upon your intentionally vague statement?
The bottom line is that you either adapt or bend over and take it in the ass. If Houston is going small and chucking up threes why can't
A) The Spurs beat them at their own game
or
B) punish them inside with their size advantage
It's all about one team imposing their style of play on another, which is how it always is in sports. Are the Rockets too quick or are the Spurs too big? It always comes down to who executes their style of play the best.
In short...go yourself
