Good linebackers take on and defeat second-level blocks. I don't understand this board's obsession with this. Gap assignment football means the LB plays half of the blocker. It is fundamental stuff, and any professional LBer should be able to do it. Sean Lee is an HoF talent because of it. Here's what good LBers do against untouched OL on the second level
Williamson running right past it and shooting the gap:
Harrison in the gap-side shoulder and blowing up the play - fundamental:
The problem with the Cowboys' linebackers is that they have absolutely 0 eyes and no ability to shed (though LVE has done it at times). This is why they constantly get killed on misdirection. But the idea that NFL linebackers just run free is totally false. Teams do not care about run plugging DTs, they care about stopping LBers from running.
Teams want to do no more than combo block on defensive tackles. That last clip showed what a defensive tackle can do if he can survive the combo. In that case he took on the initial punch and then just squeezed the offensive guard into the running Gap.
Had the linebacker not taking on the fullback the guard still would have been in the way from that squeeze.
It's a symbiosis and what I don't understand is why people are all or nothing. defensive tackles help linebacker play because it's easier to make reads when they're holding the point of attack and not getting shoved back into the second level. Then of course if you can force double teams that makes it even easier.
I'm with you 100% on the linebacker's not using one arm technique or double arm extension or trying to juke or pretty much anything other than the run wide technique to take on blockers. I've seen them both do it though is the issue. I cannot explain what's going on with Smith because it's like he just decided he didn't want to take on blocks anymore.
When Bucky Brooks talks about the lack of accountability on the defense under Mike Nolan I think that that needs to be exhibit a for that argument.
Between that and Vander esch's health linebacker is a huge need. Lbe doesn't run that well either which is a concern.
