Interesting piece by Jimmy Conrad from ESPN/Soccernet, worth a read...
I'm in agreement that US Soccer could thrive without the structure of traditional US sports ie- player drafts, conferences, and playoff formats. Conrad asserts that going to an EPL style 2 X 10 team table system complete with regulation is a step in that direction.
The ideas as presented are half-baked, but he's dead nuts that the system here needs something to boost interest. Not playing by the rules could help. The danger is the MLS standing pat between NHL and Major League LaCrosse on the US athletes' (and fans') radar. What is there to lose? Fans aren't walking away at this point, and I think the owners/towns that are really passionate about soccer could build their teams and fan bases from the ground up.
