Then maybe you can show us the article on the Cowboys technique that shows it's "very different".
Why so salty?
I don't recall you making an appearance in this thread, so maybe take a look at it and read the article linked (if you haven't already).
Validation that the Packers Hold Every Play
To sum up, the GB tackles play a hands outside technique and the "first thing they do is grab". So essentially they're keeping guys in front them by taking away spins, swim moves, and speed. The downside is they'll be more vulnerable to the bull rush, but with a guy like Rodgers, that's not such a bad thing.
I'm sure if you think back you can surely envision Tyron playing elbows down, hands inside the pads. And what makes him so effective is that he has the great footwork to keep in front of his block most times, in addition to freakishly long arms to keep the defenders hands from making a good push.
But the biggest difference between the techniques is that hands outside has historically warranted more flags, and for a pretty simple reason.
It's easier to see actual holds.
When you're beat and your hands are outside of the guys pads it's easy to see jersey stretching and there's also a lot less question of whether or not the defender just slipped, or if the defender is the one doing the grabbing/pulling.
But for some reason, the Packers aren't being called for holding as much as they should.
