The reason is very simple...Travel teams on LI don't like to play each other--thus the desire to travel to hinterlands for tournaments---because if they do poorly against each other, it reflects on the bottom line. And because they all have to sell the product, it is imperative that each is considered the "elite" LI travel program.
Like a pizza guy saying his Sicilian pie is the best around, but not wanting to have a taste test with other shops to prove it. Keep those customers coming into the store, while still pounding your chest.
