Need to win in the regular season and playoffs to get to the SB these guys had over 1000yrds for there respective teams in the SB years
"1,000 yards" is not a standard of greatness. A good season, even a mediocre season, can get a player over 1,000 yards. Let's look check an example of this.

Rice in 2012 had 4 games of 100 yards, 2 99 yard games, 6 games below 50 yards. Actually, when Ravens went on their win streak in 2012, it was the stretch they barely used Rice. He also didn't tear it up in the post-season either outside of the Broncos game...
You can even look at Blount - he was a great goal line guy, but he only had 3 100 yard games and was incredibly inconsistent in terms of yardage after that and did very little in the playoffs. There is a reason he's bounced around the league. You bringing him up actually helps our argument, you don't need a stud RB that will want top 5 RB money to win Super Bowls.
Lynch is an outlier who had the benefit of playing with the legion of boom. Yeah, when we have a great defense built and a franchise QB, then maybe we can start talking about the skill positions.
