When you hear of great NFL players who have become great NFL coaches, the guys name who I think of is Zach Thomas. I dont know if Zach ever has thought about coaching after his career ended, but his work ethic and knowledge of the game is amazing. Future hall of fame QB Peyten Manning called him the smartest player he has ever played against. Just a thought , but seems like a no brainer to reach out to Zach for any type of defensive coach position you may have available. Even if just starting at a linebacker coach position!!!
