Have often have you seen a PI get waved off because the ball was uncatchable? It happens but is very rare, it when the ball is well over someone's head, that was not the case here. If the ball had been thrown short and I am holding you not allowing you to come back to the ball and it lands 3 feet in front of me, its not an uncatchable pass because I did not allow you to come back to the ball. Whether Brahmer had a chance to come back and make the catch does not matter, the DB was grabbing him and throwing him to the ground before the ball was intercepted. That is all the matters, it's hard to say it was uncatchable when the ball was intercepted right in front of him.
