I used to do it in my old book. It's fun during a Sunday Night game, or Monday Night game, lines are posted in between plays, literally giving you seconds to choose. It's very easy thought.
It would be like Drive Result : Touchdown +400, Field Goal +650, No Score -115.
and,
Next Play : Run -115, Pass Completion +130,
or will there be first down - 275,
Thanks PC - where did you play all those. BetOnline, Legendz offered nothing and Bookmaker only offered updated sides and totals throughout the game. i won on Under 70.5. lost on Pats +6.5 (bad bet i know) and won on Saints -20.5 +125. i must say that it was fun.
