My problem is that the rules for things like roughing the passer and pass interference are very vague. Here is what constitutes defensive pass interference according to the rulebook:
Quote:
Actions that constitute defensive pass interference include but are not limited to:
(a) Contact by a defender who is not playing the ball and such contact restricts the receiver’s opportunity to make the catch.
(b) Playing through the back of a receiver in an attempt to make a play on the ball.
(c) Grabbing a receiver’s arm(s) in such a manner that restricts his opportunity to catch a pass.
(d) Extending an arm across the body of a receiver thus restricting his ability to catch a pass, regardless of whether the defender is playing the ball.
(e) Cutting off the path of a receiver by making contact with him without playing the ball.
(f) Hooking a receiver in an attempt to get to the ball in such a manner that it causes the receiver’s body to turn prior to the ball arriving.
B through F are fine. They outline specific matters that define pass interference. But part A is vague. It basically gives the green light to use even the slightest contact as grounds for pass interference. That's where the questionable calls come in.
If you look at the rules, you see a lot of incidental and inadvertent judgments being included. That's where refs screw up.
Here's another instance with roughing the passer
Quote:
No defensive player may run into a passer of a legal forward pass after the ball has left his hand (15 yards). The Referee must determine whether opponent had a reasonable chance to stop his momentum during an attempt to block the pass or tackle the passer while he still had the ball.
How can the referee correctly determine that? The only person who knows if he had the ability to stop is the player himself. Again, more subjective judgment.
What about possession. This is the definition in the NFL rulebook.
Quote:
To gain possession of a loose ball that has been caught, intercepted, or recovered, a player must have complete control of the ball and have both feet completely on the ground inbounds or any other part of his body, other than his hands, on the ground inbounds.
If the player loses the ball while simultaneously touching both feet or any other
part of his body to the ground or if there is any doubt that the acts were simultaneous,
there is no possession. This rule applies in the field of play and in the end zone
Does Calvin Johnson have complete control of the ball during the catching process according to the rules?

He controlled the ball throughout the process of catching and had both feet in the field of play in the end zone. The play should immediately be stopped right there. The catching process is finished when those feet touch. It is a very clear and obvious touchdown. The roll afterward should be considered equal to spiking the ball after the catch. That was an outright blown call.
