Many factors contribute to the attendance issues but coupled with the Dome's shortcomings from a fan experience angle I think this one is huge. The games are just too long with way too many long breaks in the action. The TV timeouts, review stoppages, and injury timeouts all need to be dealt with differently in order to dial back the stoppages. This would benefit football in general. I really think they need to cap the amount of review time to a fixed amount per half. Couple that with some kind of target, say 30 seconds, for a review. If you can't make a determination in 30 seconds, the call on the field stands. If you use up all the review time, say 5 mins per half, the game is called on the field with no further review. Injured players should be removed from the field of play, by stretcher if necessary, as soon as it's determined it's safe to do so. Spine, neck, or head trauma is obviously the exception but an arm, hand, shoulder, knee or ankle...get him off the field and wind the clock.
