I'll start off with the 2nd qtr one first. the first play are you talking about the 4 yd carry that got called back at that time stamp?
This is a basic Pin and Pull. The first rule for the pullers is uncovered man goes between C and G. The TE blocks down to seal C-gap player while tackle picks up overhang LB and then the G/C picks up first opposite color jersey and seals him to where he is pushing. IF he comes upfield, take him that way. If he tries to wrong arm, then seal him down. The RB will follow his lead blockers and cut accordingly. Thats a simple description for what is happening.
On this particular play, we have a few issues. Our TEs are not the best blockers. Another aspect of our run plays is we are down lineman priority running team. That means we defeat the men with their hands in the dirt first with combo blocks. Four hands on Dlineman and 4 eyes on 2nd level player. Our problem this year has been we do not do a good job of combo blocking. Our Driver (blocker who resets the defensive lineman) sticks to him way to long and does not release in time to pick up the reading backer or safety who is coming down based on the down block. This in turn, more than I like, has our Driver cutting in front of our runner to pick up the 2nd level defender who has put himself in a good position to force the ball back in. Kills our runners choices. Elite linemen can do this...we're missing a couple of those guys at the moment.
On this play, Bates does not seal the End and allows the End to keep his shoulders square. In turn, Ben (Driver) ends up putting both hands on the End which pulls his shoulders and turns him which kills his chance to have a good angle on the safety over top. Thus, he scrapes over and gives Dieter a bad read. Dieter then tries to pull up into the gap that appears because Ben crosses his face to indicate a hole there. BRob's job is to follow the ass of his lead blocker. The problem here is Dieter should of gone out to the Corner and BRob follow him out. Not only that, but Bates, who I love and hate every game because of this, gets destroyed because he has bad feet. Thus, Dieter runs up causing everything to pile up (what the defense wants) and the free corner and the 'proper tech used' DE kill the play. The only thing BRob could of done different was bounce it outside, but his angle left him with a free corner staring at him and he chose to go up. Since Coleman was square to the line and making a great block, Dieter should of gone off his ass and taking out the corner and Brob would of had a bigger gain.
A reminder...defense reacts to what is happening on the field after their first couple of steps, which are quite fast mind you at this level. Strength, speed and technique can kill an offensive play quickly. Think Myles Garett or Parsons as examples.
I'll just edit and add that first play. This one we don't need to get into too much detail as its an ugly penalty. But I will tell you that BRob cuts based on the helmet of the LB on Bates. Think of the old drill you see coaches do with the bag and they drop it to one side of the other and the RB cuts off of that. Same thing here. The head of the LB is inside, so he sees leverage and cuts accordingly. The DE on Coleman does a great job of gaining separation from Coleman with locked arms and just sheds him as BRob comes around. Also, you see a good example of combo blocking by Cosmi and Wylie. They work well together more times than not.
