OK, I’ll admit it, I think the Broncos are legitimate after they rallied to defeat the Patriots on Sunday. No luck was involved in the victory, unlike in Week 1 against the Bengals; and they didn’t need a fortunate defensive stand, like they did against the Cowboys in Week 4.

But can it last? The Broncos have a history of good starts that eventually imploded (albeit, with another coach). If they can hold off the Chargers, they will win the division, but I just don’t see the Broncos as a team that can win playoff games against AFC teams that, frankly, are more battle-tested. Their next big test, perhaps bigger than against the Patriots, will be Monday night against the Chargers.

– The 49ers failed miserably against the Falcons, but Mike Singletary’s influence is still obvious. Dre’ Bly loses a fumble on an interception showboating, then apologizes to his team like no other player has apologized to his team before. The culture is changed — would Bly have been as contrite pre-Singletary? The Niners are like the Broncos — good enough to win the division, but not quite a viable playoff contender. But look out in 2010, when Singletary’s approach has really set in.

– The Chiefs’ throwback Dallas Texans helmets were cool. The Broncos’ brown and yellow uniforms, not so much.

– Was last year just an aberration for the Titans? They were so resigned to their losing Sunday they brought Vince Young in. Everything that seemed to work so well last year — the defense, the running game — isn’t this season, and there seems to be no relief in sight. I wonder, if the Titans had won Week 1 against the Steelers if they would have had more confidence over the last few weeks.

– Finally, with so many teams in disarray, the Bills might be in the most trouble. How do you lose to the Browns 6-3? I admire Terrell Owens’ restraint, but something amazing must be imminent from his mouth. And for once, he might be justified in complaining.
