Of course not. And if a higher ranked guy like Gregory, Fowler or Ray are sitting there at 22, they would be hard to pass up. But it's interesting to note actual NFL success for edge rushers does compute pretty consistently with these SPARQ type measurements. For whatever it's worth...
In this case I've been looking at it as an opportunity to grab an impact edge rusher @ 22, as some of these 2nd tier guys have all the tools for success. Namely, I don't think Gregory, Fowler or Ray will be on the board at #22, yet the guys that may be - Bud Dupree and Owa Odighizuwa - may actually end up better players (possibly) than the first tier guys.
And finally, we know the Steelers only use this type of data to back up what they're seeing on tape and in workouts. So the numbers on their own mean very little. I wished they would have looked at it a bit harder before making a decision on JJ....(see fogdoctor's post above)
