Not to disparage any of the great players..but it was a different game before unrestricted free agency that started in 1992.
Teams could be built and players had no movement, QB's might throw the ball 20 times a game?
Just look at the old steeler teams, great defense big back to ground and pound, and a couple great receivers same with the 49'ers and cowboys.
Today you have a salary cap, so teams have to do their homework building a team. The Pats got that covered
