Former Cowboys defensive tackle Tank Johnson has agreed to a one-year contract with the Bengals. The Bengals are hoping that Johnson will have the same type success he once had in the Bears' 4-3 defense. He'll play the three-technique for former Cowboys defensive coordinator Mike Zimmer.
He never was a good fit in Wade Phillips' 3-4 defense. Coaches told me he tried to guess way too much and wasn't good about maintaining his gap responsibilities.
