I agree, in theory, but after having worked in Vegas sports-books for six years, I can say that there is always a team in every set of odds that the book is rooting for to win...Look at this year's Super Bowl...When Seattle won and the game total went over, the din of champagne corks popping was heard in every sports-book back room in Vegas...
No matter how hard any of these off-shore sports-books work the prices to attract "even" wagering, come game time, the bookies will have teams they will be rooting for...
PS, I haven't seen any of the Vegas books put up prices for the Frozen Four, just off-shore sports-books...The main reason for this is that most of the line makers in Vegas don't know **** about college hockey, so they won't risk the potential loss...
PPS, Sports gambling is illegal in AC casinos...This isn't the case, however, in the alley between the casinos...
