Because I have nothing better to do...
From 2000 thru 2023 294 QBs have been drafted. I have no idea how many were signed as UDFAs.
Of all QBs drafted 45 have made at least 1 pro-bowl, but not always while they were with the team that drafted them. 18 made it to the Super Bowl (6%) . 10 won the Super Bowl. The 18 include Colin Kaepernick, Rex Grossman, Nick Foles, Matt Ryan, Jared Goff, Jimmy Garopollo, and Joe Flacco. Foles and Flacco won.
69 QBs were drafted in the first round 29 were selected to at least 1 pro-bowl. That means only 16 QBs drafted rounds 2-7 made a pro-bowl appearance. Dak is one of them. 11 first round picks made it to a Super Bowl (15%), and 6 have won at least one Super Bowl.
Over that period the average number o QBs drafted per team is just over 9. The highest number of QB drafted by a team is 14 by the NY Jets. The lowest is the Dallas Cowboys with 6. They are tied with the KC Chiefs.
The teams with the highest number of QBs drafted are the Jets, 49ers (13), Patriots (13), Commanders (12), Broncos (12), Browns (11), and Chargers (11).
The Teams with the fewest are Dallas, KC, Falcons (7), Colts (7), and Seahawks (7).
The data clearly shows the earlier a QB is drafted, the more likely he is to be good (shocker!). But his draft position doesn't make him better. He is drafted high because he is more talented.
The data also shows that it is exceedingly rare for any QB to make it to the Super Bowl. But good teams have gotten there with QB who were good but not great. Two have won it. There is also no denying teh QBs like Tom Brady and Patrick Mahomes elevate their teams. I might put Aaron Rodgers into that group too, but maybe just a step behind.
What does all of it mean? I think a good QB is necessary to win a Super Bowl, but I also think with the exception of Tom Brady and Patrick Mahomes, he also needs a good team behind him. I think Dak is better than Rex Grossman, Nick Foles, Jimmy G and some of the others who have been there. He just needs a supporting cast. Maybe Patrick Mahomes and Tom Brady don't, but they are rarities in the NFL. In 24 years only 2 of them have been drafted. The chances of finding a better QB than Dak in the draft is smaller than the chances of finding a QB who is worse. Then again, Maybe Dallas gets lucky in the next draft.
BTW, one other thing I spotted in the draft data. Stay away from USC QBs. If Caleb Williams succeeds in the NFL, he will be the first in the last 25 years.
