The list of highly drafted QBs that bust is too long to post. When it comes to drafting franchise QBs, nobody knows anything more than any NFL fan. Not Andy Reid, not Parcells, not Belichick, not Shanahan, not KOC/KAM, ... Nobody.
Almost all NFL fans would agree that Caleb Williams is the best QB in this draft. I am one. I would give up 3 Firsts for him. I'm not certain he will be a great QB, but he has the best chance. I could be talked into grudgingly giving up 11 and 23 for Daniels. After that, I would not trade multiple firsts for any other QB in this draft. They are all huge gambles. I actually like Darnold as much as any of them. To give up multiple first round picks for a huge gamble when there are still holes on this roster is hubris.
