I watched "Americas Game", featuring the NYG. There was a lot of direct commentary with Strahan and Coughlin on the documentary. Strahan straight up stated that he hated Coughlin and was at a boiling point. So they had a conversation and a transformation took place in Strahan. Strahan gives Coughlin a ton of credit for his success on and off the field. If they didn't have that man to man conversation, they never would have won that Superbowl. In a nutshell, I really don't see a need for a liaison position. You have trusted coaches and players that convey the plan and ease tensions. After that, there's the man to man. If that doesn't work a decision needs to be made.
