This news doesn't come as a surprise. Guenther has already been mentioned as a "sleeper candidate" in the Eagles coaching search. Here's what we wrote about Guenther:

The 44-year-old Guenther is a native of Richboro, Pennsylvania. After coaching Division III Ursinus from 1997 through 2000, Guenther was hired by the Washington Redskins in 2002. He's been with the Bengals as an assistant since 2005. Cincinnati promoted him to defensive coordinator when Mike Zimmer was hired away by the Vikings in 2014. The Bengals have allowed the fifth least points and the 12th least yards in 2015. The Eagles have mostly focused on offensive coaches in there search, but Guenther could be a candidate to watch.

Guenther is just one of quite a few candidates the Eagles are set to interview. For the complete list, click here.
