We're right around the point in the season where "It's still early" stops holding up as a reason not to panic. It is still early in the NFL season, but it's not THAT early, and some early-season impressions are starting to congeal into realities. The Chiefs might well be unstoppable. The Eagles might well be in trouble. The Titans might well need to mix in a touchdown every now and then.
The Browns might be legit?
Yeah, we're getting to the point where the overreactions carry a little more weight, because they might turn out to be for real.
