Yes Fayetteville beat South Pitt last season after being considered huge underdogs. Any team out of the west was going to be considered that. As to the LC/Fayetteville game from 2020, Fayetteville won by 2 scores. The 2019 version of the LC team could have named the score if they played the 2020 version of LC. Not only did the 2019 team held the class A Mr. Football to one catch, they also shut down a D-1 Va. Tech commit and made him look silly, apparently running the same play at him at least 10 times late in the game.
Anyway, we can argue this all day, but it still doesn't change the fact that Fayetteville didn't play and LC won it all.
