Well...
You are likely associating running with not rebounding and playing defense. I believe that a team that is built appropriately can be successful even when playing at a faster tempo.
I feel that the current rules with defense (some zone allowed, can't back down your opponent, limited time in the lane for the offensive player) combined with the increased height and athleticism of the players make it harder to score in the half court set. Your offensive efficiency rises sharply when you are able to run.
Golden State leads the league in three things right now:
Pace, Defensive efficiency, and record. Playing at a high pace with good defense has translated to an .861 win percentage.
Will it translate into playoff success? Not sure, but the formula has been dominant so far this year.
Really the poll to me is do you want the team geared towards "Slow, Medium, or Fast" pace (since the poll associates pace in two of three options)
The ironic thing is that San Antonio has been in the top 10 in pace a few times and not so in others. Trying to associate a specific team to pace doesn't really work.
