Trying to determine holding on a still picture is pretty worthless. Your are missing too much context. Just because a jersey is stretched doesn't mean he had a step taken away. If you don't see the ball in the picture you don't know where it is in relation to the click which could impact whether it impacted the play.
For example, one of the pictures appeared to show a restriction by an interior linemen from behind as the runner approaches the hole. If the runner is tackled near that block no advantage is gained so no foul. Plus, the U in the background can't see through the bodies to see that action anyway.
On the photo of the action in the back of the end zone I believe someone said the ball was on the air to a different receiver. If that's the case and there is a restriction here, what advantage is gained by this defender? None so this wouldn't be a foul regardless of that other receiver catches it. Just another example of why a still picture doesn't tell the entire story.
The blocked punt was a crazy play. I bet that shows up on our training videos this summer. When I saw it live I thought the defender was so far offsides I was surprised they didn't shut it down. I only saw one replay from an angle and it did look like he didn't cross until after the ball was snapped. I'm guessing the line judge was fooled like me. I want to see the potential false starts again because the view they showed from behind looked like there was early movement. I saw a GIF with a sideline view and it appears that movement was pretty close to the snap. That's why I really want to see it again. The only you have a neutral zone infraction is if the offensive player was on the line and adjacent to the defender in the neutral zone. The potential false starts by Alabama were all backs so that wouldn't apply. It would be a dead ball foul so if that's what they meant to call, they would have shut it down. It was just a screwy call all around.
