Yeah Daniels will move the chains a lot with his legs year one but the risk with him is trying to get him to settle in the pocket, and the question of once you get him there can he get it done without relying on his mobility. If his OC over-uses his legs to move the chains he also might not survive year one.
Maye is an athlete but he shouldn't have as hard a time settling in the pocket. I expect Daniels to have a stronger rookie campaign, as is often the case with guys who are the most dangerous runners from the pocket, but long term Maye certainly has room to be the better QB.
Williams simply has it all. Question with him is all about whether he's gonna do the work, which is a question all these guys share of course. But it would not surprise me if in five years we are talking about one of the other QBs as the best of this class. My bet is that guy will be Penix.
And that to me is a real testament to the quality of this class. In terms of talent it is a loaded group IMO.
