I don't know about the DEs. After watching last Saturday's game I'm beginning to think Bo doesn't want his Ends to rush upfield at all. They're just there to contain the pocket while the DTs do all the heavy lifting with sacks and run stoppage, unless the run goes around the outside and then they're OK to get involved.
Turner and Allen were capable of much more upfield attacking than they did last year, and so is Meredith and Ankrah this year on the flipside of Allen. Despite that, we see the DEs dancing around with these Tackles all the time, not disengaging, holding their position. I saw this every single game last year, and even though we found out later that Allen was all banged up, I never heard that Turner was as well, yet here we are the next season watching the same thing happen (even if it is just one game).
Time and time again last year Bo and/or Carl made the point that Suh's outstanding year was all the more amazing considering the fact that the role of the DT in Bo's defense wasn't to be an attacker, it was to contain the middle of the field and stop the run. But time and time again we saw the DEs holding the line while Suh (or Crick) bull-rushed the QB.
Maybe I'm just missing something, but I don't think so. I think we're being hornswoggled.
