In deciding how important the home field advantage is in NFL football wagering, it is worth considering the winnings of the home teams, which is about 60% of all the games straight up. To counteract this, lines makers adjust the home advantage by 3 points. It will bring down the 60% and sports bettors will continue to have an edge.
Therefore, one must learn to build one's own home field advantage into the NFL football betting equation relying on statistics and match-up histories. Importance of a game to a good home team is one of the most vital factors while looking at in NFL football betting. Teams in conflict for the playoffs late in the season will receive no extra home field advantage.
In the case of teams with little or no sellout the home town fans could have already begun turning on their team towards season's end. This will involve a hostile home team advantage. Thus, the three point differential in creating a line will thus not apply here either.
In NFL football betting, the second half of a season will play a greater role in shaping any strategy where the home field advantage is concerned. Sports bettors may consider adding a point or two to the home field advantage if the team is very good. Similarly, sports bettors might not add home field points to a sub par home team.
There are some other important factors when reviewing a home team's advantage:
Grass players v/s Turf players- Obviously some teams will play better either on grass and some on turf. The home team will always play well on its home surface so sports bettors should review the past record of the opponent's ability to play on that surface.
Weather - Weather will play an important factor in determining NFL football betting especially during cold winters. It is not only about freezing conditions, but about ball handling. Warm weather teams may thus be at a terrible disadvantage. A cold weather home team, no matter how bad they might be, hosting a warm weather visiting team with temperatures will always receive at least a 3 point differential in the line.
There are teams that do not fare well on the road and playing on one of the more hostile stadiums is bound to give the visiting team an even greater disadvantage. Lastly, sports bettors also need to review the past three years of home team statistics.
