1997 or 1998 PV would beat 2018 Graham by 2+ TDs. The gauntlet PV ran in 97, beating the D1 champ (Appalachia), the D3 champ (GC) and the D4 final four team (Lee) is unmatched IMO. The 1998 team returned mostly everyone and again went undefeated and won the state title may have even been slightly better. But hard to argue 1997. They beat Lee, who made a deep D4 run, 48-8. Beat D3 champ GC 25-6. None of the first six opponents including Lee and GC scored more than eight points. Beat Powhathan by three TDs in title game. One close game all year, the epic win over Appalachia to end regular season (Appalachia had also beaten D3 champ GC). The rest were 18+ point wins, including playoffs. Hard to win six titles in nine seasons without some great teams, but only 97-98 went back to back undefeated.
I'm bias, but that PV group in 97-98 was the best team I've ever seen in 2A/D2. I think 2016 Appo, 2007 Gretna and the 94-95 PV teams were all just a little notch below. Gretnas run is right up there with PV, winning five in what, eight years?
