I don't know how many people here are on Jason Staples' patreon, but he posted a really damning take on the final play. You can see it easily on the broadcast footage, though...
Look at Robinson (10) just loafing down the field. He's right there with 9 for Jax...and you can see how he just watches as 9 takes off to throw a block to secure the score and he just has no interest in putting in any sort of effort until it's WAY too late. If he had run with his man, he would have been in position to make the stop. Just get him out of here...play someone who wants to play if this is the level of effort he's going to put in.
