I learned a long time ago that comparing outcomes against common opponents is generally not an indication of anything.
Against weak run defenses the Eagles seem to score a lot and score very quickly. Against stronger defenses the Eagles take more time to score. With the first, the impact is that the opposing team has more offensive plays and if you have a player like Karns has, that player is going to have more opportunities and the scores will happen. With the second, the opposing team has less opportunities, which ends up being a factor in how many points are needed by the winning team.
If the Eagles limit mistakes and it's more of the traditional type game where the Eagles are methodically moving the chains verses the 1 to 2 plays to score (... which is what the last few games have been ... ) I can see this one going either way.
If it follows the pattern of the last few games - maybe between the teams they can set a record for most point scored in a high school football game. This is not meant to downplay the defenses of either team - just that is what the trend has been with the last few games and I think both of these teams can and will score.
I could be wrong but I don't see either team shutting the other one down offensively.
