I was simply pointing out that in a more traditional defense guys lower on the depth chart might not get many reps at all, if any. But the way that Tuiaki played things last year gave many more people the opportunity for significant time. That's it. Stop looking for attacks where they don't exist.
By the way, I was listening to a podcast of one of the 960 shows from earlier this week and Cam Jensen was saying that he thought Tuiaki might be doing less of the full-on hockey-style substituting this year. I don't recall why he thought that, but I thought it was interesting in light of this conversation. Maybe we won't see as much this year.
