After watching a couple of next year's gameplay videos, it's clear that while OL/DL interactions have been improved, there's still tweaking needed to make them much more realistic.
First off, defensive lineman are usually taught to play "run first", meaning that they are the primary people to stop run plays before they go into second level (Linebackers/Secondary). They aren't worried about the pass so much, because that's not their job. You are not going to see a defensive lineman drop back and defend a hitch route or cover the flat (
traditionally, I know there are some exceptions).
With a "run first" mentality comes
GAP RESPONSIBILITY, which means each defensive lineman is responsible for their own gap, and they
MUST be there to plug it up so that the ball carrier has no choice but to bounce to the outside where the linebackers and secondary can "trap" him and make the tackle. (Trapping is when you have two to four players coming up on the ball-carrier at different angles, thus "trapping" him, leaving him with nowhere to go).
Watching the videos, it doesn't currently look like the lineman are "slanting" to their gaps, they are merely slanting over and then getting occupied by one lineman, which is a big no-no.
Secondly, defensive lineman are taught to play
LOW. Both offensive and defensive line coaches PREACH that "the low man wins".
Here is a picture of the lineman in their stances...
They are clearly sinking their butts and ready to take their flat step towards the gap and play low, right?
Wrong.
They stand straight up and run towards their gap, only to get held up and occupied with a single offensive lineman.
Here's what it
should look like:
Both offensive and defensive lineman have a lot of knee bend here and are playing low, trying to get their pads underneath one another. They clearly have forward momentum, and their shoulders aren't straight up, they are almost parallel to the turf.
Secondly,
GET HANDPLAY INVOLVED! Once a defensive lineman is engaged with an offensive lineman, they don't just extend their hands on the offensive lineman, thinking they can win. They are taught after you take your first step, c.ock your arm back and deliver a blow. Rip, swim, spin, ANYTHING! Defensive lineman do NOT LIKE hands on the pads. Offensive lineman are taught to extend like that so they can steer you away from the play easier, without you being able to get a move on him.
Please pass this along, maybe the development team will read this and get some ideas going for next year.
If anyone else has some suggestions or ideas, feel free to throw them out there,
