The script will change on you real quick if you don't take care of your mega stars. As stated above, AD can easily retire. He can hold out. He can demand a trade. Take care of AD. The Rams have already established a culture and reputation that this organization is different. They take care of their players (for the most part) even when they part ways.
An extension may not go much further in years than his current contract (2 more years guaranteed), but he needs to be taken care of because his teammates have shown they can't consistentliy beat one-on-one blocking with or without him.
