I personally think the refs have become too involved in the game. They are deciding too many games. Not due to final plays... but momentum changing plays within the games. Typical "no call" situations are becoming flagged. I mean honestly... offensive holding, false starts (leaning, flinching).... it is well known that offensive holding can be called on every play. How many times have you seen a defender held and no call? Which begs the question, when it is called.. why? Is it PURELY subjective? If so, that's a BIG problem.
