Misleading stat. Since 2011 these first round QB's have won a SB
-Eli Manning (11)
-Joe Flacco (12)
-Peyton Manning (15)
-Patrick Mahomes x2 (19 and 22)
-Matt Stafford. (21)
So that's 6 first round QB's doing it. Brady winning 4 in that time frame, Wilson winning 1, and Wentz (who is a first rounder) going down so Foles could do it is what really throws that off. Since 2018 Mahomes, Brady, Stafford, Mahomes, 3 of 4 have been first rounders.
Then when you talk about making the Super Bowl you can add
-Peyton Manning again (13)
-Cam Newton (15)
-Matt Ryan (16)
-Jared Goff (18)
- Patrick Mahomes again (20)
-Joe Burrow (21)
Only the 2013, 2014, and 2017 (because Wentz was injured) Super Bowls since 2011 didn't have a first rounder as one pf the participants.
So the breakdown of Super Bowl winners since 2011 goes
1st round: 6
2nd round: 0
3rd round 2 (Wilson, Foles)
4th round 0
5th round 0
6th round 4
7th round 0
So even with a crazy outlier called Tom Brady, the 1st round still produced the most Super Bowl winners at QB in the time frame.
When you go by participants it is more eye opening because out of a possible 24 it goes
1st round 12
2nd round 3 (Kaepernick, Jimmy G, Hurts)
3rd round 2
4th round 0
5th round 0
6th round 5
7th round 0
Conclusion: the first round is still far and away the best round to get a QB if your aspirations are to win a Super Bowl if you can't draft Tom Brady.
