John DeFilippo — better known as "Flip" — was the offensive coordinator for the Browns under Mike Pettine in 2015. That year, believe it or not, three Browns quarterbacks combined for 3,782 net passing yards.
That's a huge number for a team whose quarterbacks were Josh McCown, Johnny Manziel and Austin Davis. It's also the third-highest in Browns history, behind the 2018 team with 4,007 net yards and the Brian Sipe-led team of 1980, with 3,915 yards.
Of course, the 1980 team was much more impressive because that era was much more run-dominated.
