Early 2010's you mean..stats were still normal in the early.to mid 2000s and even late 2000s. It really changed in 2011 where the pinball numbers became common and multiple rookie QBs entered the league excelling when that was pretty.much unheard of aside from Dan Marino, Peyton Manning and Big Ben.People got used to the video games numbers since the rules changes of the early 2000s. Defenses have caught up a bit and there's also a lot of bad QB play.
People forget what the stats used to look like.
