I'm not sure "choke" is really fair. Yes he did flub up the call of the "not-catch" early in the game which led to a TD but the wheels really started coming off when Purdy got hurt then Johnson went out with a concussion later in the game. After all, he did manage to get the team to the NFC Championship on this THIRD STRING QB. And similar to the Cincy/KC game, the refs didn't do them many favors especially later in the game (Greenlaw's Peanut Punch penalty being one).
And as far as Reddick goes, he's been making NFL level Tackles look bad all season let alone TEs.
