Pop did not go small because the Mavs were going small. The Mavs aren't small (Dirk is a 7' PF, Dampier/Diop are 7' Centers) - but what makes the matchup bad is that the PF plays mainly a perimeter game while the SF likes to drive and play off the dribble. The Spurs went small because they did not want to put Rasho, Nazr, or Tim on Dirk on the perimeter - which is a good idea because you don't want to leave a superstar shooter wide open all game. Dirk is the star, and if he is wide open the team has no problems with him shooting 60 times a game (and he can make 50 to 60% of wide open shots). What i'm saying is that you can put the extra big on Howard at the SF but tell the big to sag off near the lane to take away any driving angle from Howard. What will happen is that Howard will have a few wide open shots, but he is not nearly the shooter that Dirk is plus since he isnt the superstar there is no way he is taking 40 to 50 shots a game. Dirk would have a fit and the team chemistry would be shot if he did that, and he wouldn't be comfortable with it. Therefore he would make a few, miss a few, but eventually try to drive or would play off to Dirk or the rest of the team. That leaves the Spurs with two bigs near the paint for defense, rebounding, shot blocking, etc. It also makes Dirk guard in the paint on the center while the Spurs are on offense since there is no way that Howard would be on the center. Dirk hates guarding in the post and a good physical center can test him and pound on him down low during the game (hopefully Javtokas can at least do that if he comes over). That will wear on Dirk and help take his legs away for late in the game or series. Or the Mavs will have to go to a bigger lineup to protect him - then the Spurs have them right where they want them. Basically you are giving the Mav's small forward open shots and taking away the dunks and easy layups. Even if Howard shoots 40 to 50%, that is still a lot better than giving Howard, Terry, Stack, and everyone else wide open lanes directly to the basket for 99% FG dunks.
