I used one example. Deebo being out is another. Chris Carter is basically a placemat compared to Harrison. Not only does he generally hurt us being out, it also allows teams to cheat their TE over to the right and help out with Woodley whenever they need to.
I hate to use this analogy again, but in today's uber-complex defensive schemes, you can't be thinking in checkers terms to play chess. Every little thing has implications 5 moves down the line. ONE PLAYER makes a difference, and we were out 2 key players (Clark was also out and Troy was STILL very effective).
That's why I'm not worried yet. The DL's job is to occupy blockers to filter things back to the LB's, and shortages in the secondary have meant that we've had to cheat those same LB's back into coverage more. When we are 100% healthy, with Clark and Troy on the field, and Harrison back at OLB, and we have problems, then, and ONLY THEN, will I be concerned. Right now there are mitigating circumstances. Trying to assess this defense right now is not possible.
