Not sure I following you here.
Twins or trip formations means there are only 6 gaps in the box, so a 4-2 alignment is enough if the defensive players maintain gap integrity and don't get destroyed by the OL ... And is more than enough if you are playing 2 gap, as the backers are schemed to be "free" in that situation.
The issues against the run last year were based on talent (guys not good or strong enough) and player gap assignment error. The scheme was fine, IMO.
Do you think that was due to more confidence in the LBs in zone coverage as opposed to the inexperienced CBs? Or perhaps overcompensation for the porous run defense (which was MUCH worse earlier in the season when Porter was out)?
Part of the reason we sucked against the run was BECAUSE we kept our OLB's on the slots. We took our 7th man out of the box. We only had 4 D-linemen and 2 LB's in the box against the run. Your guys up front have to be beast for that.
I'm not concerned about gaps, I'm more concerned about numbers.
If they line up in 2x2 or Trips, there's 7 offensive players in the box versus our 6 defenders.
By using a QB as a running threat, he becomes your 6th blocker cause he voids out one of your defenders within the front six. The DE or a LB has to honor the QB, thus he can't chase any inside run by the RB. The offense will leave him unblocked. (he's voided against any inside run)
Now what we've got is 5 blockers + a RB against 5 defenders.
Now, if you can 2-gap then this doesn't become such a problem. I agree with you on the talent thing. However, if you bring an extra defender in the box then you don't have this problem. You now out-number the offense.
This is really good stuff.
If I can find some of my posts from last season, I said that if I had been an opponent's O-Coordinator, I'd spend 45 minutes basing every package out of these formations. Teams like Notre Dame and K-State didn't even have to throw the ball into massive windows because there was no reason to increase the risk. Instead, they had a numbers advantage inside. Against baby defensive linemen. Against baby defensive linemen being asked to play a man's technique. With LBs behind them who couldn't get proper depth. And, a back 7 that didn't know how to pass receivers to each other. And, some Safeties who had zero range.
Look, I have no idea if D'ono is a schematic genius or not, but it's hard not to acknowledge the perfect storm of trying to transition to a certain system and doing so with exactly the wrong type of players (partly because of their talent and partly because of their age).
