I've been burned so many times by those pro-style QBs throwing pretty balls from clean pockets that I just gave up on them.
In the modern NFL, it seems like a physically average, really polished technician maxes out at like a Kirk Cousins, Tua, Jared Goff type level. And if they can't process fast enough to beat a pass rush, the floor looks more like Mac Jones.
Give me a guy who can create on his own and beat a defense even if they make a good play. If I'm going to draft a pocket QB, he had better be Peyton Manning "superpower" level at pocket play (think Joe Burrow), or at least be dummy productive.
Ewers and Beck look polished, but if they're playing on top 5 teams with NFL teammates everywhere, they had better be shredding. The playoffs will really help separate the wheat from the chaff, once more NFL-caliber talent on defense starts showing up.
