There is an old saying among coaches and people around the game that, generally speaking, you can chalk up your end-of-season win-loss record in part to how many rookies you have in your starting lineup. For every rookie you have starting under you, you can expect to lose one game as a result.
The Pittsburgh Steelers this year have had three rookies playing for them in the starting lineup for more than half the season now, all three representing their top picks in the 2016 NFL Draft, and all of them coming on the defensive side of the ball.
