Yeah, I'm not sure you understand how this works.
The "public" doesn't line up at casinos with a number in mind, waiting to hit it as soon as it opens. And even if they did, Joe ########s betting $100 a game can't move books off a number. That's what syndicate(s) do, mostly syndicates that are backed by nerds with pretty sophisticated computer programs.that have a number in mind, and pounce when the right one gets posted.

My guess is that sharps would come back in at SEA +3 (Sportsbook.ag, a square book, has SEA +3 -115).
That said, the public's
