At his first function as the new head coach of the St. Louis Rams, Steve Spagnuolo handled himself like a pro.

He was classy, appreciative, professional and sounded as if he would be a huge success in St. Louis. Perhaps this should not be so surprising. The New York Giants have a history of turning their defensive coordinators into top head coaches. Just go back over the years.

Tom Landry was the Giants’ defensive coordinator before becoming head coach of the Cowboys. Bill Parcells held the same post before becoming head coach of the Giants, Patriots, Jets and Cowboys. Bill Belichick also had the title before becoming the Browns’ and Patriots’ head coach. John Fox, too, was the Giants’ defensive coordinator before becoming head coach of the Panthers.

Now Spagnuolo makes the same jump as some of his predecessors. Early indications are that he, too, will follow in their headsets.
