In the NFL teams list, which is no surprise is under the NFL Teams List link on Lines, has all the teams in the NFL and their records, stats, and betting info. What you will see in the list are the teams, G (games played), SU (straight up record), Win %, ATS (against the spread) record, Units, O/U/P (Over/Under), Over %, Under %, PF (points for) PA (points against).
The straight up record in the NFL teams list is something that you, obviously, need to and should know, but the betting info is what Lines really has covered and is vital information when making bets on games. If a team is a great one, but is not good at covering the spread, i.e. does not have a good ATS record, than they may not be a good betting team. Lines gives you this info as well as all the info on Over/Under records.
The points for and points against shows you how good a team’s offense and defense can be and this is important, as you can stack that up against another team’s offense and defense in looking at a NFL game you want to bet. For example if a high scoring team is playing a team with a weak defense it is more likely that the game will be a high scoring one. Sportsbooks know this and will set the O/U accordingly, but you still have that info before you lay some green on a wager.
