, this should be the last thing you should worry about when you're contemplating making a play. Look at recent form, recent head to head results, over/under trends if your betting totals, etc. Don't worry about who the public is on unless you see lines move late indicating late sharp money, but sharps don't always win, so just do you're research on stats that matter and make the play you think is right. On what side the public is on should be of very little importance in your decision relative to the various other stats.
This is a Post-Time decision if the gate opens all betting is closed so look closely at the opening line! The Oddsmaker is rarely wrong. You can drive yourself to drink trying to figure out your loses so concentrate on the winners and don't try to pick all the games.......
