Bit late to this, but...
Hughes seems to have a good natural raw skillset and be pretty well rounded. The problem is he makes a lot of really dumb decisions.
Having said that, a lot of his mistakes remind me of Josh Allen's worst games, especially in 2017...where he was absolutely pressing and trying to play hero ball. Difference is that Josh was a generational talent who could occasionally come up with a highlight reel play in the middle of his boneheaded interceptions or fumbles. Hughes, on the other hand, doesn't quite have the ability to get away with some of the shit Josh pulled.
But we need to not miss the forest for the trees here and realize the entire thing is a dumpster fire. We've all watched beautiful, on-target long throws be flat out dropped by receivers. At least two of his INTs were catchable balls that were tipped by receivers into defenders' hands. Etc.
He's got no WR support, he's got no time thanks to the dogshit OL, and he's got a mediocre run game to rely on. He's also got an OC/QBC directing him who is underperforming, and we all know the issues with the HC. On top of that, the defense isn't doing his squad any favors and puts more pressure on him. Throwing him under the bus is....disingenuous.
We've seen this time and again since JA17. Talented (or at minimum, serviceable) QB struggles due to a variety of systemic issues. We screech for them to be benched. New QB comes in and lights it up for a couple games because no one has any tape on them (among other things), and then it's back to the same dumb shit.
Not saying Hughes doesn't have any issues because he certainly does, but I highly doubt putting in Simms or Drube is gonna make a difference for more than a couple games. Continuing the QB carousel of the last near-10 years isn't gonna do anything.
