A lot of the pre draft criticism was that he didn’t throw downfield a lot. Oregon ran a ton of WR screens and underneath stuff so a lot of people thought they were covering for some kind of lack of downfield accuracy. Herbert also had a (somewhat) earned reputation for folding in big moments. For all the great plays he made, it was understood that if you could pressure him, he’d crumble. Honestly, I thought he was a good college QB but nothing special in terms of NFL ability. But I’m wrong about these things all the time so nobody should be paying for my opinion.
