It's only trolling because I know its not realistic. I would absolutely do it from a purely strategic POV
Your strategy IMO is wrong and significantly short sighted. I'd rather play a Sunday night game in a raucous playoff road environment, see what my team has or doesn't have and what we still need to work on. I'd want to see Flacco against a top flight defense. And I'd want to put my players in a position to succeed. Also, a win would be a HUGE boost to this team. It would make them more intimidating in the WC round and would mean the offense has progressed another step forward (or the defense dominated without Smith).
Also, an injury in Week 14 is much better than an injury in Week 15 or later. In your scenario there is a chance we have to play out and win Week 17 in a meaningful way, putting all of our players at risk in that game. If we can win this game, we could avoid that risk altogether, AND any injuries that were only 3-4 weeks would return in time for the playoffs. In your scenario, the potential delay of those injuries is worse.
Lastly, I like Cinci to gun to injure players without remorse more than Pitt. Pitt might be a tough opponent, but generally speaking (outside of Mike Mitchell) I don't think most of those guys are dirty. Alternately, Burfict 100% dirty, Iloka a clear headhunter. Those guys could be out there recklessly running around at that point.
Of course, you would run scared and forfeit. That's what you do. When things don't go your predicted way you don't post, you don't appear. You only come out when it fits your narrative. Just like when I tried to take your +165 playoff bet, you ran scared and bailed and revoked your offer claiming "it's only for Gabe". It's trolling because you've decided meaningful analytical conversations (which you used to engage in) are no longer necessary. Instead, advocating for teams to forfeit games to avoid injuries is actually the better posts we get from you these days because you at least admit to your trolling ways.
