History shows that players still on the board after the third round might be better off going undrafted entirely than getting picked in the late rounds.
The teams at the top of the draft are examining every aspect of the QBs in the class, knowing that the chance of failure is still high. "Most of them are mistakes."
Imagine a world where the Vikings trade up to draft Drake Maye, putting the QB in the same division with Caleb Williams and Jordan Love.
