Yes..there are people in this thread who have only tackled their pillow and are lost watching the video.
I looked up this Carroll/rugby stuff and Seahawk site confirm what I said - they are teaching old techniques and using rugby gimmick as a way to provoke interest. They made video to get the head out of tackling. They confess their past tactics were wrong,
Rocky Seto, the Seahawks’ assistant head coach has worked with Carroll since 2001. He said:
"If you’re high school coach or a Pop Warner coach, it’s a new game. When I was playing and even coaching early, I was taught to get my head across a tackle, or see what I hit, which in effect put my head in the line of fire. It has worked beautifully in terms of getting guys down, but now we know better.”
Exactly - football tackling coaching was getting screwed up. Carroll describes how they went back to basics:
"We just feel like it’s important for the game,” Carroll said. “We’re trying to always help out, in particular in keeping the game safe. We’ve been doing something for a long time that we had never really shared before. It was something we had learned, just through ball—it’s an OLD STYLE CONCEPT of tackling. When we connected it with rugby, it made it even more fun to grow with it."
There you are...they went back to old basics and tried to make it sexier with the rugby frosting, There is NOTHING NEW for football in what the video shows. Its just dusting off what was forgotten. The main purpose of Carrols video (which is meant for schools etc) is to get the head-leading out of tackling- to reduce helmet to helmet tackling and yes bring the shoulder back. The hip stuff is secondary
" Rugby players have done a tremendous job at taking the head out of the tackle in their game, and they truly exemplify shoulder tackling.
