The theme of the 2010s and 2020s in college football has been power concentration. Things have grown pretty predictable, with Alabama winning six national titles in 12 years under Nick Saban; Ohio State, Clemson and Oklahoma ripping off long runs of conference domination; and now Georgia winning back-to-back national titles.
It's early in the College Football Playoff's lifespan, but it's possible that we're witnessing a concentration of power at or near the top of the sport, something that expansion to a 12-team CFP might or might not address. Or it's possible we're just witnessing another, similar act in college football's history -- it is, after all, a sport that has forever been lorded over by a ruling class of dominant schools.
