I think that any team can play the game provided a working drive train. A box on wheels can be a valuable alliance partner at the regional level if its team has the right strategy and a driver who practiced--and if your robot is a box on wheels, your driver is probably pretty practiced.

Of course, I have seen teams without working drive trains... but those are rather rare. I wouldn't say there are a large number of teams who can't play the game... the vast majority can't play the game well, but that's another story.
