Great stuff. Eventually the defenses were going to catch up to the offenses. Ebb and flow. Players back in the 20s and 30s and even into the 50s were much slimmer. There were very few, if any, 340 pound behemoths. But like you pointed out with the Titans, eventually size will come back in style once teams see an edge. When everyone is small/hybrid, big and plodding will come back.
