You can't avoid the contributions of a Rodgers or Murray. You can muster your resources to try to minimize their impact (just as teams muster double teams to try to minimize a Watt), but the QB and RB are still going to do hundreds of plays worth of damage, and the records and overall strengths of the units they play on reflect the impact -- and thus the value those contributions have to generating wins and preventing losses.
Help me understand your point here.Are you saying a defense can't focus on the rb every bit as much as an offense could game plan for the DE?
I think that's what he is saying and I believe it.
A defense can certainly focus on stopping an RB, but that doesn't stop him from successfully contributing his specific yardage gaining skill 300 or more times a year. There are even some games where great RB's (or QB's) are successfully limited in what they accomplish.
But even the best DL, no matter how successful he is at winning individual battles and beating schemes, only contributes his specific offense-thwarting actions 80 or so times a year.
To make the case that such a player has as much value to his team as a prolific offensive player such as a workhorse RB or star QB, you'd have to show that all the times he wasn't making plays, he was commanding so much attention that
it was elevating the rest of his unit to elite levels. With HOU, that was clearly not the case, because they simply weren't an elite D by any meaningful metric.
I'm quite sure the rest of HOU's D was better than they would have been with a replacement level DE instead, but while helping to raise the overall level of your unit to mediocrity is nothing to sneeze at, it's also not the stuff of "most valuable in the entire league."
Best player? Sure. Most valuable? Hard to make the case.
