I think if they played 10 times, it would be pretty close to 5-5. But the overall winning margin over those 10 games would be 2014 +6-7 points. The 2010 would never blow out the 2014 team, but in a couple of the games the 2014 would beat 2010 by 14+ points.
Also if we are judging both teams by how they were playing in the Rose/Peach game, the 2014 team would win by 7+. They had figured out some of the defensive issues by that point and the defense was just plain nasty with an offense that was a freight train (occasionally off the tracks)
Can you imagine what Pierson, McFarland, Chucky, Carraway, Dawson, Mallett, Carter and Kindred think of this 2021 team? Watching freaking Foster, Armstead, Caesar, Jenkins, Cooper, Harris, Hodge avoid contact and screw around all game every game?
