Other NFL Markets
Bookmakers will price up a wide variety of player markets, which they may call props (short for propositions) such as a quarterback to throw more than 14.5 completed passes in a match, or a running back to gain more than 97.5 rushing yards, and spread firms will offer similar markets in their own style.
Plenty of information is available on player statistics at nfl.com and other sites but it is applying the basic player history to the game in question that can pay off. For example, it would be foolish to take the over on a rushing back's yardage gained without checking the success level the opposing defensive line has had in limiting similar players in recent games.
And don't forget that if you know something, the coaches in the game will know it too. What happened in the past does not govern what will happen in the game you are betting on.
The best example of this is the NFC Championship game of 2000, when many punters thought the conservative New York Giants offence would be outgunned by the pyrotechnic attack of the fancied Minnesota Vikings.
The Giants had other ideas though and came out with an explosive passing game they had never before demonstrated. This caught the Vikings on the hop and the Giants trounced them 41-0 (another example of a good defence beating a good offence).
First touchdown scorer generally offers bad value except for very rare occasions when market-makers have missed a likely tactical change or a piece of injury news. With so many runners, what might look an appealing price compared to a football first-scorer market is no such thing.
Bookies often price up highest scoring team markets from a selected band of six or eight clubs (spread firms offer similar indices) and these can be boiled down to a couple of potential bets using the steps described in the total points discussion.
