It means there is action that direction,but the question is,is that money correct,or are the people who bet the number down from 155 on the right side?Each game has action both ways.Last thursdays NIT final the total went up 2- points in ten minutes right before the game and that money was wrong.Someone probably made a couple of big bets at Pinnacle.Make your mind up,don't be a "line chaser",it doesn't pay.GL
