There’s an old cliche that in football that games are always won on the line of scrimmage. Sure, the skill position players get all the attention, but it’s really the big uglies that affect the outcome the most.
I generally think that’s an outdated concept. The explosion in offense in the sport has allowed good coaches to scheme around any perceived weaknesses, and dynamic athletes, particularly in college, can dominate a game in ways that used to not be possible.
That’s not to say an imbalance in line quality can’t be exploited, though. Elite pass rushers and behemoths on the defensive line can make lives hell for an overmatched offensive line.
