Preseason football is all about working on a variety of different areas to prepare for the trials and tribulations of the regular season.
One area which teams work on more often than you'll see in the regular season is the 2-point conversion. Offenses use the opportunity to fine tune their red zone offenses.
Those extra points gained - or lost - can be the difference with such small spreads in the preseason. Through the first two weeks of preseason football, seven teams have attempted the 2-point conversion.
You can probably expect the majority, if not all, of the 25 teams that haven't run a 2-point conversion play to do so in the final two weeks of exhibition football. That one point could be the difference from your pick covering - or failing to cover - the spread.
Here is a list of those seven that have already worked on 2-point conversions:
St. Louis Rams @ Cleveland Browns - The Rams failed on their 2-point conversion.
Washington Redskins @ Tennessee Titans - The Skins successfully converted a 2-point conversion.
New England Patriots @ Philadelphia Eagles - The Eagles successfully converted a 2-point conversion.
Atlanta Falcons @ Baltimore Ravens - The Ravens failed on their 2-point conversion.
Buffalo Bills @ Minnesota Vikings - The Vikings failed on their 2-point conversion.
Tampa Bay Buccaneers @ New England Patriots - The Pats successfully converted a 2-point conversion.
Tennessee Titans @ Cincinnati Bengals - The Titans failed on their 2-point conversion.
