Those are the standard answers (expense and difficulty/ timing in our season), but I still would think we'd have at least a few more teams.

Mike, That's like asking what color is the sky is and when told blue you respond with... no that's too obvious it has to be more complicated than that.
As for the US Olympic teams... how many have a bonafied shot at making it onto the water in 2016? Two maybe three teams? So with that 30% of the teams are there. If you still want to know why they aren't there ask them. Asking here is not going to get you an answer even remotely correct.
