The absurd thing is the notion that this is no change. If the defense fails - yet again - this year, the same people who are acting as though it is no change at all will be using it as an excuse for Jason Garrett and Jerry Jones.
Parcells said it was a huge change. He said it took his scouts a couple of drafts just to understand the types of players that are needed.
Pat Kirwan - love him or hate him, he talks to more GMs than almost anyone on the planet - said that the rash of teams switching to 3-4 the last several years was for 2 reasons. More teams were in the 4-3, so the pool of players better suited to play in the 3-4 was deeper. Also, the most important piece in the 4-3 defense, a disruptive 3 technique DT, has become the most difficult player to find apart from QB. He said it used to the be the Demarcus Ware type that was hard to find....now it's more difficult to find a Warren Sapp type.
Do we have a disruptive 3 technique? I don't see him. I don't see a DL not named Ware that causes much concern for a defense at all. Certainly not Ratliff. With most of the other guys, it's wishful thinking and projection, none have proven much, other than Spencer, who has proven he could be mediocre until a big contract was on the line.
