Well, sadly, we have the lowest total points scored (152) of any winning team (I'm not including the Ravens because they play tonight). We have also been outscored by our opponents this year (160), even though a third of that came in one game. So aside from the Patriots aberration we're outscoring opponents 145-108 (average game score of 20-15). Not bad. Plus our three losses are to teams that are a combined 22-3. We haven't exactly had the toughest road in our wins though, with our victories over teams that are a combined 13-28!!! That's a glaring number right there. And only 1 of our 5 wins is against a winning team (Detroit). Could we be the "weakest" team with a winning record??? I think we might be.
Other contenders IMO: Detroit, Tampa, Jacksonville
