Saying those early teams weren't genetic freaks is not true.Guess you didn't watch the 2015-2018 title games. Long TD passes, strong running game and great defenses. 2017 game freshman QB threw for 4 TD's in first half alone. Blocked punts for TD, fake Punts. The past few years they have relied on the run primarily and you see what happened. Those first 4 teams were not genetic freaks, they were complete teams with mixture of talented players who bought in and set the standard. I would argue that the more recent teams have more raw talent but not the team mentality of the earlier championship squads
At one point both the QB and RB were going to Ohio State. You had a Michigan OL. You had a safety who is dominating the MAC. There were also many other D1 players there. Those teams were loaded. Don't kid yourself.
