JBragg, you and I always seem to find ourselves agreeing on this point about line movement every month or so after a game has just finished when people either (a.) jumped off a play because of line movement (or "reverse line movement") or even (b.) jumped on the other side (the so-called "sharp side") and then the "public" team cashes.
If you like a game, play it. The players don't care about line movement this, line movement that, etc.
