It's the occasional "wow" play that made the difference. I don't care what anyone says, you can't really project a Rodgers or Mahomes trajectory. Not really. But I do believe that Packer brass thought they could clean him up but retain the break-the-pocket, throw on the run stuff and bail us out when the play breaks down that Tim Boyle, for example, is just never going to do. Which is essentially the same thing as when they elevated Rodgers over Craig Nall.
The team eval of him is really part of a broader pattern. We saw it with Gary and Savage as well. They see traits and then say, I don't care if he never did it in all his snaps, we can make him do X, Y and Z. I comprehend it but I don't think it's the best way to do things. Drafting players is about obtaining a player that basically doesn't exist (yet), but that sort of thing can only go so far before it devolves into magical thinking.
