No.
Hard truths:
Sean McDermott's teams are soft and can't handle a challenge; they buckle when they face adversity, pressure, or expectations
Josh Allen has no poise and becomes a terrible quarterback when things start going against him
Can't win an SB like this, ever
Also, this team does not have an advantage playing in cold weather. The more physical team is the one with the advantage, and that's usually not the Bills
This team needs to play in a dome to be at its best
Also, can you imagine Josh Allen in a Super Bowl when faced with adversity? I don't even want to think about it.
