What's different that is of significance is the rules regarding the QB.
You can't hit him like you used to.
You can't hit his receivers either, but there are tons of receivers who can take advantage of the rules. You don't need a Beckham or Brown, or even a Julio to win a SB. As long as you have one of those rare elite QBs like Brady, Rodgers, or Brees then you're golden.
So its all about the QB and disrupting the QB. You can have the greatest secondary in the world but if you can't disrupt the QB he will beat you every time.
So I ain't buying what Davis is selling. Parcells said you can disrupt a QB more from the DT position than from the outside.
More than any other player, Joe Greene made the Steelers great. I'd take him over Lawrence Taylor.
