We aren't asking the right questions.
Bryce is a decent QB. The Panthers are finding out that having the correct pieces around him is required for him to be successful. That means a good running game, competent receivers and a sturdy offensive line. Bryce can be a positive contributor in those conditions.
A couple of further improvements and this could be a playoff team. Bryce could be good enough to help the Panthers get there.
But he's not enough to get the Panthers to the Super Bowl let alone win it.
So, the missing option in the poll is "He's good enough to help get the Panthers to the playoffs, but not the Super Bowl."
