Agree re these click bait offshore props like the Miami QB one. I was talking about Vegas generally. And, yes, you'd be amazed just how accurate Vegas gets it on a regular basis (the line setters, not the gamblers themselves). It ain't due to luck!
These early off shore lines have super low maximums and don't mean much. They're basically just like gambling's form of clickbait. Having said that, from a general sense, Vegas knows a whole lot more than most people realize.
