Just one example, Adrian Peterson did it with a bad coach and a bad QB. Another, Kamara did it 2021 with bad QB's and no WR's (Michael Thomas was out injured all but 3 games) and still made the playoffs.
AP was drafted almost two decades ago and the Vikings didn't win anything until they had Farve. He is also a HOF RB. So that's what it takes.
AK had 900 yards rushing and 400ish yards receiving. That production is not nearly enough to claim he lead us to anything. 2021 was a team year that was lead by our defense which was ranked 4th.
