I thought the same thing. In situations like this, I will wait to see what the public and the line tells me. Sometimes the line will stay the same and the % of vegas vs. public will even out. Other time I may miss a point or two, but it normally doesn't matter if it's lopsided and my gut is right by the time I waited. However, this method is useless for someone that doesn't look too far into reading lines and betting with vs. against the public, if that makes sense?
