I look at 2020 Bama and wonder if they got everybody's best effort that year because of COVID. Yes, Bama had to endure the same issues as everybody else and should get credit for overcoming all that and dominating like they did.
But ultimately there will always be an asterisk next to anything accomplished in 2020, and it should not be considered the equivalent of a championship in a normal season. Bama never had to play in front of hostile crowds. The playoff teams they faced may possibly have been over-rated. Who knows if Notre Dame and OSU make the playoffs if they play their normal schedules. And even if OSU was one of the 4 best teams, I mean really how could have Ohio State been at its best with the limited number of games they played that year.
How many teams did Bama play that had players sitting out due to COVID? I honestly don't know, but it makes me have doubts that I should trust Bama's resume. So I am sorry, I would have trouble voting any team from 2020 as the best overall.
fwiw, i went back and looked (as best i could), and i don't think any team was materially affected by covid for bama. went to wiki 2020 bama season, and went to each teams wiki page to see if/when covid affected the team.
first, the bama/arky game was postponed by a month and tacked on at end of season due to arky having covid the week prior to facing bama. after the postponement, they played 2 other games prior to facing bama.
second, no other team bama faced had a game postponed prior to playing bama for covid affecting
their team. a couple, i think, had a game rescheduled due to their opp having covid, but not the team that faced bama in the next week or 2.
third and final, someone mentioned osu having only 55 players for the cfp. i can't find any sources for that (didn't search hard, tbf). i have no reason to doubt it either, but i can't find a reason for it.
obviously my "research" could be lacking, but i do remember discussing with friends how it was amazing we didn't get hit with effects from covid like most teams' seasons did.
