The Browns have had their foot on the pedal since the season ended in searching for a new coach. They've interviewed several college and professional candidates, but Zimmer is just one of two defensive minded coaches that have been seen by Cleveland.
Zimmer is considered one of the more brilliant defensive minds in the league, and his work with the Bengals defense speaks for itself this year on their way to a Wild Card appearance and a top-ranked defensive line. But despite his expertise, Zimmer has been known to be less than political when speaking his mind about players, coaches and potential bosses, which may not be the best fit for a head coach position.
The NFL Network has also reported that the San Diego Chargers are interested in Zimmer, but no formal interviews have been set up.
Bengals offensive coordinator Jay Gruden has also been mentioned in the conversation for hiring multiple vacant coaching positions around the league, including an interview with the Arizona Cardinals and Philadelphia Eagles.
