I am not too sure that would be in the best interest to the team. I believe the IRDR rule is to be used only once a year per team and I am not to sure we would want to use it on a second string back. . Scenario Eli tweaks/ breaks his thumb in weak 3 we need to bring in a QB then the IRDR would be best used on Eli. . I feel the IRDR is best used on the #1's used in key positions.
