There is no guessing when it comes to what area of the Pittsburgh Steelers was the weakest link in 2018.
It was the defense.
But outside of the players on the field, where plenty of blame resides, you have to wonder who is more to blame for the issues on the defensive side of the football? Would it be head coach Mike Tomlin? Or defensive coordinator Keith Butler?
The easy way out in this debate would be to say they both have their hand in the defensive issues, but you have to dig deeper into the roles of each to know who is really to blame.
