If you're really gonna get into statistical analysis, Dolfan984, there is a lot more that goes into pass defense than the secondary, and interceptions. To fully evaluate the Bills' secondary you would have to look at QBs completion percentages against the Bills, passes defensed by the secondary vs. completions made. Then there is the effect of a defensive line, which I would submit was the real weakness of the Bills defense last season. If a defense can't consistently pressure the QB, without using constant blitzing, the QBs are always going to be more accurate, will throw into coverage less frequently, etc. In addition to not defending against the run very effectively, the Bills' line had a hard time pressuring the QB. Aaron Schobel had something like 6 sacks as a rookie, but as a team the Bills were well down in the standings at getting sacks of the opposing QB. Defensive line pressure will always make a secondary look better. The lack thereof will make a secondary look worse than it is.
