Zod, I was reading through the thread you linked and wanted to comment on the defensive scheme post you had. You quoted Steve Young saying that he loved seeing man to man defense. He really didn't specify if it was a press man or an off man scheme though.
I want to bring up the Miami Dolphins/Oakland Raiders game back in 2002. IMO, Miami's press-man scheme totally dominated the Raiders offense that day. The press at the line disrupted the timing of the Raiders passing offense. They forced Rich Gannon into making turnovers and bad throws, and Jon Gruden didn't attempt to offset this with the running game. Basically, it was a day where Jon Gruden was outcoached by Dave Wannstedt.
Miami's defense is a 4-3 chase scheme. They rely on their front four to get pressure, so they want defensive ends with the speed to rush the passer around the edge. They line their ends up wide and have them rush up the field on most snaps. This allows them to get consistent pressure with those ends, and it also makes it difficult to run on them to the outside. They rely on two big tackles to collapse the inside pocket and occupy blockers inside, which allows the linebackers to read and flow to the ball. The linebackers all all off the ball and line up inside the ends, and their main assignment is to simply flow to the ball. The Dolphins also disguise their coverages more than some people think. They press at the line on 90% of the snaps, and they will run a cover 2 man under scheme with the press as well as a cover 4 zone with that press. The basic premise of Wannstedt's 4-3 scheme is to create turnovers and get the offense back on the field.
