I think you're spot in with your evaluation of Richardson. Have to believe he could excel in a McDaniel offense.
What other quarterbacks do you like? I haven't done a deep dive on the position.
Love Young's game, but I do worry about his size - particularly since he's not particularly fast or explosive. Don't like Levi's game that much, but I think he's a better athlete than given credit, you can build something around his strengths imo. Somewhere between Herbert and Tannehill but closer to Tannehill. I don't love Stroud. To me he's in the mold of Goff, Mac Jones, Rosen, Haskins. If he proves to be more athletic than that, I'll reconsider his standing. To me, though, he's the least interesting QB of the group - and probably doesn't deserve to be considered part of the group.
I haven't given most of the QB's a hard look yet. But, I feel pretty comfortable with these guys and Hooker - who is not exciting as a prospect imo.
Richardson is definitely #1
Between Young and Levis, I think it really depends on your team and offense, but both offer enough to make an early investment - assuming the situation is right. For Levis, I'd want big, physical targets (Atlanta?), and I'd want a great OL for Young. He navigates the pocket well, but his size could see him overwhelmed without good pass blocking. He plays more similar to Burrow than Tua, so I don't think he'd mitigate a bad OL as consistently as Tua does.
I see varying degrees of elite traits in the top 3, but I don't know if I see any in Stroud. Could be a me-problem.
