To fix/reduce the number of RB check downs, we could add a sliding scale in the misc section where the higher the slider the faster the QB checks it down to the RB and a 0 on the sliding scale causes the QB to absolutely refuse to check down. Make it so that the RB is not an option to throw to even if he is running a route aside from using the check down.
This adds more gameplanning customization and allows people who like to throw alot of flares/swing passes the option to continue doing so and vic versa for those that dont.
