There's plenty of examples over the years of runners especially in the 70's, 80's and 90's producing with subpar passing games. Marshawn Lynch put up consistently big rushing numbers from 2011 to 2014 with a below average to average passing attack. In 2011 he put up over 1200 yards and 12 TD's with Tavaris Jackson and Charlie Whitehorse at QB. Murray outproduced McFadden twice and once behind an OL in 2013 that had yet to add Martin. The OL was strengthened even more in 2015 by adding Collins.
Murray put up a franchise record 253 yards in 2011 behind a transitioning OL. As for Jamal Lewis he got 300 carries because he was producing just like Murray got almost 400 carries in 2014 because he was getting it done. McFadden's wasn't named the starter in week one and wasn't receiving many carries because he wasn't producing. He only got his opportunity to start because Randle got hurt and was released.
You are so far out in the left field you can't even see the plate.
You have yet to name a RB who hasn; been All Pro, much less a Pro Bowler, much less is AVERAGE.
You've also covered 20 years for your LOTS of examples.
Dude, just stop while you are behind.
Lynch averaged 4.0 yards per carry and 61 yards for game for Buffalo.
McFadden was at 4.6 yards per carry last year and 68 yards per game even when he wasn't a starter added in,
As a starter he averaged 87 yards per game.
OH and Beastmode is NOT AVERAGE.
