You keep trumpeting this narrative as though being comparable to Darnold or Allen is some sort of positive. Both those QB’s played typical mediocre to poor rookie campaigns and both their organizations are still in full blown “Hope” mode. Both of those two QB’s may well remain average at best or bust completely. If Rosen showed Mayfield quality last year, you might have a point, but he didn’t.
You value Rosen based on his college resume and are choosing to completely ignore his rookie NFL campaign. No GM has done this (not should they), which is why he was so cheap. Whether you want to accept it or not, the FACT is that Rosen is indeed a second round pick now and must fight to prove he is worth even that second round value.
I'm not quite sure why you're being so combative about this.
If Rosen showed Mayfield quality last year, he wouldn't be a Miami Dolphin, and Kyler Murray wouldn't be a Cardinal.
And there is no narrative under which Josh Rosen was, is, or ever will be a second round pick. That's...because he was picked in the first round.
