Am I crazy for starting Brissett over Mayfield?

I know it sounds crazy, but Brissett has put up good points in each of his starts, and should be having to throw the ball a lot against the banged up 49ers defense.

And I looked and no QBs are putting up good fantasy numbers vs the Bills. Not even Mahomes or Maye.

I just seriously think Brissett is the safe play.
