Talent wins championships.
There are many out there that praise the virtues of developing talent and building a cohesive team, showing resiliency, etc. And yeah, those things are true too, but generally speaking, the teams with the most talent win the most games, including of the championship variety.
It’s no coincidence that the teams that recruit consistently at a high, high level are the ones playing for national championships in college football. Alabama, Ohio State, Oklahoma, Georgia. Clemson, Notre Dame. Those teams all bring in some of the best talent, and are the teams that we see in the College Football Playoff more than others.
