This is how Asian books work, they move prices early, and make it back on volume (this is not a wholly geographical designation, Pinnacle Sports is also an Asian book but operates in the Caribbean...iirc). The problem in the US is that it is a highly competitive market so you have to acquire your customer base every weekend, and these customers don't actually care so much about prices. So having weaker prices is a more effective way to deliver the product. In addition, US gamblers like parlays, parlays are more profitable, have lower volume per bet, and (so far) the economics of the Asian book don't work for this market (i.e. get syndicates to bet your lines early).
