Interesting comparison. It seems as though you use comparative terms when somebody with an inclination to look up statistics could poke holes in your generalizations.
If you use statistics to answers some questions, such as: What are the rushing yards given up by the defense? What is the percentage of passes completed against the secondary? What is the TD to INT ratio of the QB? etc., etc., etc. You will likely find that the Bills weaknesses are not as weak as the Jets weaknesses, and the Bills strengths are stronger than the Jets strengths. I don't have the patience to look up such statistics and rankings, but if somebody had that much time and interest, I bet the statistics would help to explain why the Bills are 4-3 and the Jets are 1-6.
