I think he could get it with the #2 seed, but Stafford would have to put up a couple stinkers and the Rams couldn’t also be #1 seed.
It actually isn’t impossible that the Rams drop to a Wild Card. Seahawks are tied with them and they and still have a H2H. Also Seahawks outperformed them in the first matchup but Darnold went full Jets-mode in that game.
