If the new HC finds a QB in this draft that they really like or like better than Rattler, whether it's Dart or someone else, I'm fine with them drafting him. Nothing could turn the team around faster than finding the right QB.
And if it's Moore, one of things I really like about him is that he appears to be able to run a great offense, even a passing offense in Dallas, with mid-level talent at QB. That's the kind of thing that Shanahan did with Garoppolo and Purty and McVay did with Cousins, Goff, and Stafford.
I wouldn't dare say that Moore is the next Shanahan or McVay, but I do like that he seems to be able to make offenses work with mid-level QBs like those guys can do.
