If you’ve watched any Philadelphia Eagles game in the past couple years, odds are you’ve heard — and grown tired of hearing — the term “RPO” mentioned throughout the broadcast.

The run-pass option helped the Eagles win a Super Bowl, and offenses throughout college and NFL have utilized the RPO as a method of making life difficult for opposing defenses. Northwestern coach Pat Fitzgerald absolutely hates it.

"RPO is the purest form of communism." You can't watch football without hearing "RPO" these days, and @coachfitz51 has some strong thoughts on the Run-Pass Option: pic.twitter.com/isVYvkPCvr — Big Ten Network (@BigTenNetwork) September 11, 2018

During his Tuesday press conference, Fitzgerald lambasted the RPO as the “purest form of communism” and went on into a rant about officials missing ineligible linemen downfield.

While Fitzgerald did have a point about how the college game’s three-yard allowance for linemen provides the RPO with more than enough room to put defenses at a disadvantage, college football fans simply couldn’t get past Fitzgerald calling it communism. After all, that portion of the quote made little sense in an otherwise valid argument.

if Pat Fitzgerald had better opinions about communism and RPO's, Northwestern's football players would have a union and the team would have had at least one top-80 scoring offense in the past 5 seasons — Rodger Sherman (@rodger_sherman) September 11, 2018

What would Marx say about that? Engels would probably laugh. Lenin would be too busy trying to organize players to unite in their common goals and overrun the luxury boxes. Stalin would just have everyone shot. https://t.co/Lln9gSFpmS — RedditCFB (@RedditCFB) September 11, 2018

If you listen to the full quote … I think he means "quantum physics." Seriously! https://t.co/YRq2RaMo3r — marc tracy (@marcatracy) September 11, 2018

Did Northwestern hire Mac from Always Sunny to be their football coach? https://t.co/gp5ibrUrOt — Brian Cook (@BrianTCook) September 11, 2018

As far as I know, this is the first Communism reference in Big Ten pressers this year: https://t.co/5JdxnRPSDB — Alex Roux (@arouxBTN) September 11, 2018
