If I were overly optimistic, I might theorize that the play of all three guys is lifted when they all play together. When they're all in the lineup, Schobel mans the right side and Denney and Kelsay rotate on the left side. This could improve both Denney's play and Kelsay's play in two ways: (1) each guy is kept fresher, by virtue of each individual playing less snaps, and (2) Perry Fewell is able to specialize the two of them, meaning its easier to put them into situations that play to their strengths.
Someone pointed out that Schobel is 2 years removed from his last double-digit sack season. If I were overly optimistic, I might theorize that he just needs both Denney and Kelsay to be healthy. That last double-digit sack season was indeed 2006, the last time the three of them were healthy for an extended run. As I said above, Denney and Kelsay both being in the lineup might raise the play of each of them, meaning the left side might present more of a threat to the offense. That might open things up for Schobel, and could be why his game has fallen off since '06.
Personally, I don't think I'm overly optimistic, so I DON'T buy into my own theory. Kelsay and Denney just don't pass the eye test to me...I don't want a rotation that exists mainly because neither guy is good enough to play every down. And I want a more explosive player in that spot than either of those guys could ever possibly be.
But, even though I'm wearing my realist hat, I have to acknowledge this little theory of mine can not be PROVEN wrong. This means that, no matter how realistic or cynical I might be, I must admit that there is at least a small chance that this theory is on-point, and our pass rush stands to improve significantly over last year's embarrassment.
In other words...there is a little bit of hope here. God forbid, huh?
