Not quite. If you're trying to show it's common for starting QBs to be pulled from losing teams at the end of blow outs you've picked poor examples.
The only two that fit what you describe are Manning and Flacco (both are SB winning QBs over 30).
Palmer and Mariota were pulled before the second half of those games due to injury, Matt Moore, (as you stated) played the whole game, and Brissett came in at the end for Tolzein and took over the starting job.
It does not appear that pulling young QBs to protect them in blow out losses is all that common.
