Looks like San Francisco-Jacksonville game has a total of 40.5 with a spread of 16.5 or 17 points. Just math tells me that means they're going to call the totals for the game at 28.5 for SF and 12 for Jacksonville (or somewhere close to that).
Ever since a couple of bad games against IND and SEA, SF has been scoring 30 with regularity. Additionally, 12 (or even 13) is a terribly low total for a team that actually was looking like they were improving offensively, but you won't catch me betting on the Jags unless I get another 28.5 line.
Right now, I'm feeling SF over is a good play and probably the overall total over.
