Every year under Joseph the Cardinals have been better than average in the sack category. Every year. Even when Jones went down early in the year. The issue is whether they are blitzing a ton to get those sacks or not.
I call a duck a duck man. I've seen this same song and dance about every issue every offseason. Like I said in another thread, half the board was freaking out over the corner back group last offseason. There were those of us who were not freaking out because we said that 1) the depth was good enough 2) Keim has a penchant for veteran signings that pay off. Literally both of those things came true, even with the retirement of Malcolm Butler.
From what it looks like the Cardinals think this:
1) Last seasons swoon was a function of inopportune injuries. As the Football Outsiders rankings demonstrate, the Cardinals weren't a very healthy team last year. Injuries tend to fluctuate from year to year.
2) They can save some money and future cap flexibility by NOT signing high priced free agents and can go after the second and third wave of free agency where the real bargains are at. We've seen ample evidence that despite Keim's failings at other areas of player procurement, he excels at finding players during the later stages of free agency. I'd expect the team to chase a veteran WR, EDGE, DL.
