No one likes a perennial winner.

It's the primary reason the New England Patriots are vilified by NFL fans outside of the Northeast — Bill Belichick and Tom Brady have co-anchored the AFC's Super Bowl-winning machine for two decades and their own on the verge of another, which would mark their sixth since 2001.

At the college level, Nick Saban has developed his own brand of dominance in Tuscaloosa through a recruiting stranglehold that has resulted in an unprecedented five national championships since 2009.

Sports Illustrated calls Belichick and Saban "football's most powerful friendship" as others in the coaching profession try and mimic their level of expertise.

College GameDay analyst Kirk Herbstreit compared the two gridiron superpowers Monday on Twitter after he was asked by a follower: Why do people hate excellence?

Same reason people hate Bama and Saban—Envy. I’m not a “fan” of either but an admirer of their achievements, consistency, and excellence! Incredible to watch. https://t.co/gr36RfUG6O — Kirk Herbstreit (@KirkHerbstreit) January 22, 2018

Dynasties aren't often duplicated and as Herbstreit says, they're incredible to watch.
