If you find 2 or 3, it means it happens dozens of times. And no, you're wrong about both scheme and DL
This is simply missing his gap assignment:
Simply a blown coverage
Lack of reading keys
These are all the result of lack of vision/feel and have nothing to do with what the rest of the defense is doing. He is quite literally playing freely here.
I agree that his instincts are a big concern and might be "bad"; however,
I don't agree that these videos prove anything.
In fact after analyzing these videos and thinking through what his assignments likely were in that scheme, the videos actually make me feel better about his instincts...
Video 1:
He needs to get outside the lead blocker #86. He does over-run the play but he is not a full gap over. I would call that more bad technique than lack of instincts. He saw the RB going inside but he couldn't stop his momentum due to poor body position when moving laterally. I'm certain he was coached to error on the side on not getting boxed inside on that type of play. If he got boxed inside he would definitely be in the wrong gap.
Video 2:
The receiver he is covering is attempting to pick the other defender coming across from the opposite direction. The DB behind him reads it as going to the other crossing receiver and that DB comes from all the way over from where the pass ended up being completed to the opposite side to cover the crossing receiver that didn't end up with the ball. I think coaches would want that DB to stay in place and would want Murray to pick up the other receiver if he definitely sees the other crossing defender get picked.
Video 3:
The DB lined up inside the slot WR (defensive right) blitzes and Murray moves over to pick up coverage on the slot WR. There are 2 DB deep to the defensive right but the one to the inside that would have to cover the slot WR is Murray didn't, stayed back and then took a horrible angle to get across the field.
