I know you don’t confuse the two systems, but a lot of posters and other fans does, even including the media. That's why I wrote a post about it originally.
Also, as you might notice I wrote that Dennis Allen with the Saints incorporated a lot of 3-4 concepts while Vic Fangio with the Bears incorporated a lot of 4-3 concepts. That’s is, in my opinion, not that the same as that they primarily ran those systems. Which they didn’t, by the way, because they ran a hybrid, like I wrote, but for the sake of simplicity let’s just call it that. You are right about Teryl Austin and the Lions. That was my mistake.
The post that I answered and that you quoted was about how Kerouac mentioned the difference about how to make acquisitions to the different schemes. I assume you agree that the players you highlighted like Calais Campbell, Damon Harrison, Kevin Minter, Robert Nkemdiche, Kareem Martin and Markus Golden changed from one perceived scheme to another, and I also assume that you would agree that it would be because the decision makers from the team that acquired them felt that it was a good idea?
It’s not a problem, by the way, if my post bothers you. We can just use some of the many other examples if you want.
