Are the New England Patriots no longer considered the best team in the AFC East so far?

The Patriots are not the best in the AFC east as of right now. I don't care how talented they are, their record shows me that they are not the best. The Bills are 4-0. Whenever you go undefeated that speaks volumes. Also the Patriots were embarred two weeks ago when they were up ended by the Dolphins. The Dolphins? They could have lost to the Jest and they may still be in the standing as the best, but since they lost to a terrible team, then that signifies to me they are no longer the best. The Bills are having their time and they deserve it. Besides the Patriots can't always be the best.
