Fields still needs to show growth as a passer. I think anyone who watches recognizes that. That said, next year, when we have more resources to put good players around him, should help him tremendously with said growth. Issues such as throwing with timing/anticipatory throwing and holding onto the ball too long can at least be exacerbated by not trusting his protection, receivers, and having to do literally everything himself. I think it'll be easier for him to play within the system/take checkdowns/etc once he has more trust in the players around him.
We'll see on Claypool. I think he'll be a productive, if unexceptional, receiver. Fluctuating between an okay to solid #2, which is probably fine.
