For a man that ESPN routinely turns to for NFL insights, you would think that former quarterback-turned-analyst Dan Orlovsky knows what a percentage is.

Percentages are everywhere in football: a quarterback's completion percentage shows how accurate he is, Red Zone percentage shows how often a team scores touchdowns inside of 20 yards, et cetera, et cetera.

But apparently, Orlovsky discovered the exact definition of the term only recently, as he revealed on The Pat McAfee Show on Monday.

'Hand to God, true story. Do you guys know what percent, like the word percent, is derived from?' Orlovsky asked the confused show cast. 'How come it's percent?'

'So [ESPN producer Paul Hembekides] this morning was like, "Joe Burrow, his sack rate is four percent." And I said, "Dumb this down for me. No human's going to hear me say that and I'm going to make them smart." 

'And he goes, "Well, what do you mean?" I said, "What does that actually mean?" He goes, "Out of every 100 dropbacks, he's getting sacked four times." And I said, "Is that really what it is? It's always out of 100?"'

The cast was stunned by Orlovsky's admission, with everyone saying that they knew the definition of percent.

'I didn't know it was always out of 100,' Orlovsky admitted. 'I did not know percent.' 

While Orlovsky deals in more X's and O's analysis than statistical analysis, you'd expect the 43-year-old to have a greater understanding of a concept that begins to be taught around the fourth grade.

The UConn graduate's playing days are best remembered for one of the biggest gaffes in the sport's history.

Orlovsky, who was quarterbacking the eventual 0-16 Detroit Lions, ran out of the back of the end zone for a safety in a game against the Minnesota Vikings.

Since he retired after being a career backup, Orlovsky has been a go-to for play breakdowns on the Worldwide Leader as a member of NFL Live.

But he has also developed a reputation for being open about himself – including his grooming habits, eating habits and other likes or dislikes.
