I agree with the QB statement, 100%. Where do you rank the importance of a top RB in building a championship caliber team?
QB, O line, DE, WRs, D line, CB, Safety...Where does RB fit in?
The reality is that other than QB, there is a ton of randomness to it and there is no single player that can make a significant impact on a team's success. Beyond QB, it's all about putting together a collection of good players and a good scheme that they excel in.
I wish I could find the thread but a few years ago in a similar discussion I ran some of the numbers on correlation between having top players at each position and wins.
Surprisingly, after QB, punter was actually the position that had the highest correlation between good players and team wins. Kicker and TE were both near the top as well. DE pretty randomly in the middle if I recall.
The reality is there is just no way to know. I know there are all kinds of deep analytics on it but they seem like a huge stretch to me. There are just so many variables and trying to quantify that kind of thing is like trying to quantify how many Super Bowls each would have won if Brady played for the Colts and Peyton for the Patriots. It would be awesome if we could go to an alternative universe and see, but no matter how many absurdly complicated analytics they invent to try and figure it out we'll just never know.
There are anecdotes but they're useless. People say the last 10 super bowl champs haven't had a great RB or whatever, but those anecdotes exist all over the place. The last 15 CBs drafted in the top 10 have something like 1 career playoff win (I could be misremembering that, the exact stat was in a much more recent thread about this, less than 2 months ago probably). The Chiefs were 12-5, then got rid of Tyreek Hill and went 14-3 and won the Super Bowl without him.
The reality is the anecdotes (and likely even the stats) are probably a lot more correlation than causation, especially with such small sample sizes. The Patriots have like 35% of the Super Bowls in recent history and they don't pay RBs, so right off the bat that's a bunch of recent SB winners without a RB. I don't think the Pats would have magically been an 8-8 team if they'd paid a RB. As we've seen recently, the only thing that
really mattered was whether or not they had Tom Brady.
And the anecdotes continue on that front, as beyond QB most people think far and away the two most important positions are DE/OT. But the Browns had 15 years of Joe Thomas with nothing to show for it. And Miles Garrett makes no impact on the difference between the Browns being great or being terrible. The only time they've been good the last 15 years is when they had great QB play. When they didn't, it didn't really matter at all that they had the best OT in the league or the best edge rusher in the league.
I don't think teams mind paying good money for an elite RB, they just don't want to get stuck in a longer term deal where they're stuck paying good money for an over the hill RB that fell off a cliff. I think it's the career length and sudden dropoff guys can have more than the impact of the position. You'd have a hard time convincing me that Corey Davis or Hunter Renfrow would be a better way to spend $15M this year than Saquon Barkley. The Giants just don't want to be stuck paying Saquon that when the cliff comes.
