The Bengals drive at the end of the 1st quarter was textbook football. That convinces me that their offense has some ummpf.
Their defense was ok, but many are saying the Browns weren't firing on all cylinders. The test in Central Div will be the Steelers.
I thought the defense on both teams was a little weak, but the Browns were weaker than the Bengals there. The Browns offense was able to find holes in the Bengals defense, and the Bengals offense was all over the Browns defense like a cheap suit, unfortunately.
