Their record against the higher end teams this year is pretty damn good. Some of their best games have been against teams near the top of the league (NYI, Wash), but seeing the stinkers they put in against dredg's like Minnesota, Detroit and New Jersey (even though they won that one) shows just how far they still have to go.
Looking at their 5 losses so far, 3 of them were against the bottom 4 teams in the Central (combined record of 16-22-4 and another against Detroit (4-10-1). The only loss against a playoff team they have so far is Florida (7-3-4) after they basically busted Mike Smith's balls. The combined record of teams they've lost to is 27-35-9 which is pretty damn close to the record some recent lottery winning teams have earned in a season.
