The late Buddy Ryan was the architect of the 46 defense which led the 1985 Bears to a 15-1 record and Super Bowl XX victory. When Buddy became coach of the Cardinals in 1994, he gave his twin boys, Rob and Ryan, their NFL start by adding them to his Arizona coaching staff. Rex was a LB coach, while Rob was a DB coach. Rex would go on to become the D-line coach for the Ravens winning a Super Bowl XXXV ring in 2001. Rex has eight years of NFL head coaching experience, his most recent stint coming with the Bills from 2015-2016.  The Ryans have five Super Bowl rings and 50 years of NFL coaching between the three of them.
