On Sunday afternoon our NFL Double system side is on the Philadelphia Eagles. Game 221 at 4;25 eastern. Philly has extra prep time for this one after playing on a Thursday and taking on a Denver team that played on Monday night. There are 2 excellent systems that are in action for this one. First we want to play on teams like the Eagles that are playing the first of 3+ road games so long as they are not -4 or more as these teams are 26-4 to the spread. The other system dates to 1973 as we play against week 4 teams that scored 24 or more points in the first 3 games and won their last game. Denver fits all the negative subsets of that system as well. Playing against home favorites of 7 or more, if the opponent has at least one win and this is a non division game. We will back the Eagles who should score enough to stay within the number in this one. Take the Double digits with Philadelphia.
