But other books had already made it -17ish and took action. That’s how lines are made. They open early with smaller limits, then watch which side the players they have flagged as sharp hit. They then move the line accordingly (say, -13.5 to -14.5), and if the sharp hits it at -14.5, they keep going til the sharp guys stop.
in this case, the sharps were around -17. Yet circa posted -13.5. I’m not sure why they posted it so low, they had to know that number was gonna get hit. And it clearly did. But they either have us power rated fairly high, or (more likely) they are lower on Bama than the rest of the market. Either way, it’s a good sign cause circa is widely known to be the sharpest licensed US Sportsbook.
