Romo is criminally underrated, yes. Wilson gets listed because of his Super Bowl appearances, but those were due just as much to LoB so they’re clearly weighing his metrics pretty highly, in which case Rodgers should be #1 by a mile.
He replaces any of the four. Probably most easily Manning.
Wins are listed under the ‘team’ category of statistics. QB stats, like the ones I mentioned, are listed for quarterbacks. There’s a difference.
