Karras is the adult in the room up front. He has started 70 straight games for Cincinnati, handled 99.6 percent of the available snaps in that stretch and worn a captain's patch every season here. That matters when the line has changed around him and the quarterback situation went sideways last year. I have him at an eight. He is not the biggest or most athletic center, and at 33 he can lose isolated power matchups. But he makes the calls, keeps everyone pointed at the right defender and almost never leaves the field. This offense would feel a lot less stable without him.
Strengths: Karras is an elite communicator with tremendous durability and experience at every interior line spot. He recognizes pressure, maintains leverage with sound technique and gives the offense a consistent protection baseline regardless of who plays beside him.
Weaknesses: He is an average athlete by starting-center standards and can be walked back by top power tackles when left alone. Age raises the chance of decline, and he wins more through intelligence and technique than recovery ability.
