Hudson Houck has retired and will be replaced by former Jets O-line coach/assistant head coach Bill Callahan. Interesting thing about Callahan is that he has been a head coach in the NFL before and was one of the top rumored candidates to take over as the Jets offensive coordinator should they can Schottenheimer. Good pickup for us. Also, Cowboys new defensive backs coach is Jerome Henderson, previously with the Cleveland Browns. Not bad, familiar with Rob Ryan.
