Herbert has been perfectly average in every single per stats in the league since coming into the NFL except pass attempts, where he's number 1. 1+1 = ?I wouldn't go that far.
BUT......Herbert is having a very subpar year. The 6.5 yards per pass through 7 games is really bad. 17th on PFF, 13th in QBR. He has looked like a league average starting quarterback so far this year. His ability to get out of the pocket and make positive yards with his leg hasn't been there this year either.
