There is a difference between winning a super bowl and effect on winning. The best QB wins the Super Bowl most years.
The last 21 Super Bowls, 17 were won by Hall of Fame or close to Hall of Fame level QB's. There is ZERO question the best QB is the best way to win a Super Bowl. Not even debatable.
I think the question is which position other than QB is MOST important to winning. Nobody is saying you can be absolute garbage on the O Line and normally do well. But the NFL there is not as much different in the O Lines as there is in the receiving cores.
If you take the top 5 O lines and the bottom 5 Oline's you see an average of a 3-game difference in wins.
The other 22 lines in the middle vs the top 5 is a 1 game difference. So BAD offensive lines vs great offensive lines is an average of 3 wins. BUT the average offensive line, which is most teams only makes a 1 game difference.
Historically in the modern NFL a top 5 offense almost always makes the playoffs, a top 5 defense is a lower %. A Top 10 defense is equal to a top 5 offense. So we KNOW offense is more important than defense. Again, you can't suck on defense normally, though an average defense with a top 5 offense will likely make the playoffs but not vice versa.
Also, historically the top 5 and 10 passing offenses percentage wise make the playoffs more than the top rushing offenses.
So statistically:
While nobody would argue a well-rounded team good at everything is great there are things that equate more to success than others if you had to trade off:
-Offense is more important than defense-Not a question statistically to success rate
-Offensive line from team to team is about a 1 game difference unless you are bottom 5 in the league.
-Top passing offenses make the playoffs more than top rushing offenses
-Great QB's is the ultimate difference maker
-The 1 article only went back so far but showed 9 out of 10 of the top receivers made the playoffs, very high % better than the 1 game that offensive line gives you. See additional article below
-the evidence we have suggests receivers are more important to winning than offensive line, and mainly due to the fact there is not as wide a discrepancy in offensive lines as there is in receiving corps.
-Nobody can say QB is not the most important, I'd rather have a hall of fame QB, a top 5 offense and a 15th ranked defense than a middling QB with a 15th ranked offense and the #1 defense. You can win the Super Bowl with 1 but not the other though both likely make the playoffs.
-You can have Justin Herbert and have a terrible defense and coach and you have a losing record, obviously you can't be terrible at 1 important thing but that's a different discussion than whether WR is more important than offensive line, the evidence seems to show it is.

By the Numbers
- Out of the 28 receivers with over 1,000 receiving yards in 2023, 15 made the playoffs.
- Teams with elite receivers had higher chances of playoff success, with the 1,200-yard mark being significant.
- Among the last five Super Bowl winners, only the Chiefs lacked a 1,000-yard wide receiver, relying on star QBs or TEs for success.
Elite wide receivers are increasingly crucial in today's NFL, sparking the question of whether having one is necessary for championship contention.
