A "Politically Incorrect" Observation
When we drafted KVB, our entire defensive line (of Wads, Swann, Smith and Rice) had been decimated.
The Cardinal brass was obsessed at having someone off the right edge who stood up better against the run than Simmy Rice did. We drafted KVB in the second round - his reputation was that of a good tackler who might be able to put some pressure on the passer but who was certainly no sackmaster.
We also "got lucky" with a 6-7 UDFA (Wakefield) who could play LDE. We also started drafting mid-range DT's to help plug the leak inside and, since that strategy was not very successful, finally bit the bullet and drafted Wendell Bryant with a high pick.
That's the background. Plus one other very important thing - Over the past 2 - 3 year period, it became pretty apparent that we lacked a pass rush and were hanging our DB's out to dry.
But what did we have? Two stout-hearted "character" DE's who couldn't rush the passer plus Wendell and a bunch of other nondescript DT's. Plus, oh yeah - Dennis Johnson; our only DE with any potential as a pass rusher.
So we drafted Pace in the first round this past draft and got lucky with our 5th round pick, Ken King (who apparently also can rush the hell out of the passer). And then we changed our defensive scheme to a more aggressive one where not only our defensive linemen but our linebackers are now getting into the pass rushing act.
As much as we all loved KVB, he no longer fit the job description for a RDE (i.e. an edge rusher) and he, Wakefield and probably King would all have competed for the LDE spot (which is more run-support and less pass-rush oriented than the other side) if he had remained healthy.
KVB remained an important cog in our defensive scheme because he played a particular role (toughness against the run) and had become a spiritual leader - but to some degree he had become one-dimensional lineman (moreso given our new emphasis on getting to the QB).
He was the right man for the time when we drafted him, but I believe the Cards were starting to move in another direction anyway.
My point? KVB was an important cog in the over all scheme of things, but not indispensable. We'll be OK.
