The Difference between the Bengals and Pittsburg?

[*ochocincos*]

Steelers seemed to make a good hire for OL coach with Mike Munchak. Steelers OL used to be terrible (like their stupid towel), now it's actually decent. Combine that with a RB that is probably the most patient runner I've ever seen in recent memory and lost about 20-30 lbs to be quicker, and you have a winning team.
Antonio Brown is very good, but the Steelers don't have the same success without their improved OL and Bell.
