What’s your guys thoughts on the Rams/cowboys line movement?
Most likely sharp money. Public money doesn't move lines, sharp money does. Joe is betting $50 while sharps and sharp groups usually are hammering bets for thousands or more if they feel the line is off even half a point. Some people might disagree with me but both bookies I know told me this when I asked. Injuries can also move the lines like this if they are significant, but you're usually only looking at half a point to a point max unless a good QB is ruled out.
Some people say it doesn't matter if the line moves but in my experience, if the line doesn't move in the favor of the team I was on I lose more than I win. If the best sharp nfl bettors are hitting 55 or 56%, often times to us it feels like a coin flip, so that's why you get a lot of people saying it "doesn't matter".
