Very few QB prospects, similar to other positions, are locks to succeed everywhere. Oftentimes, it’s about the players skill set, natural strengths, and ability to execute within a system.
I did not love Bo Nix as a prospect, but he fits the archetype of what Sean Payton likes to do. He’ll be successful there, provided they can surround him with talent. He’s not a talent elevator, like CJ Stroud, but, based upon how he ran Oregon’s offense, and conceptually, the Ducks do a lot of what Brees did with NO, so the infrastructure is in place for him to do well.
