More convincing wins.
Yes, they're 2-0. That doesn't make me look at them and think "yeah, they're a playoff contender." That makes me think "okay, we crushed the Chiefs (big whoop) and just barely scraped by against the Raiders." I want to see them UP 21-3 at the half; not down by 18. I want them to play to a point where the opponents' fans aren't saying "you lucked out," but "wow, you guys played a hell of a game."
2-0 doesn't mean a thing to me. Remember when we started 5-0 a few years back...and finished under .500? Sorry, but 2-0 means nothing more than "yeah, we can still finish 2-14."
