Bengals lose assistant coach to Dolphins

Kevin Coyle, the Bengals' defensive backs coach for the past nine seasons, has been hired as Miami's defensive coordinator, the Dolphins announced.

While the Bengals would have preferred to keep Coyle, this loss would have been magnified if defensive coordinator Mike Zimmer had left as well. Zimmer was in the running for head coaching jobs with Tampa Bay and Miami.

Replacing Zimmer would be a tougher challenge than filling the void left by Coyle. The Bengals defense will remain a top-10 one under Zimmer.

The Bengals knew Coyle was going to leave at some point. Cincinnati denied Coyle permission to speak to the Eagles last season for a defensive coordinator position.

So, when the Bengals allowed Coyle to interview with the Dolphins, they knew he was likely gone, especially with his ties to Miami coach Joe Philbin. Coyle has known Philbin for years, and reportedly attended the recent funeral for Philbin’s son, Michael.
