That's not to say it won't be good, the potential is there obviously but the baseline assumptions that all of these QBs will develop linearly almost never holds true.
This time last year, Field Yates put out a mock with *six* first round QBs: Arch Manning, LaNorris Sellers, Garrett Nussmeier, Drew Allar, Cade Klubnik and Sam Leavitt. He went 0/6. That's not a dig against Yates, everyone thought at least some combination of these QBs would be at the top of this draft.
But the QB position more than any other position doesn't develop linearly, and once you put the microscope on these QBs (Sayin size, LaNorris accuracy, etc.) people will start drawing similar conclusions.
Now, it's not hard to be a better QB class than the 2026 one, that's a perfectly fine assumption to make, but some people are talking about it being a great class need to pump the breaks because a lot of these QBs aren't close to being great prospects at this point.
