If you're talking about the last TD, that was absolutely nothing like the James play. The Eagle clearly caught the pass, had possession, and took several strides as a runner. James took -zero- strides.
The first contested one, although James had 2 feet on the ground and made a "football move" that really looked like Ertz's as well. The rule is holding on through the entire catch and "surviving" the ground...which is where the Eagles got a ruling the Steelers didn't.
Again the Steelers got screwed either way and got stuck with a terrible matchup (the Jags) that the Pats deserved instead Of getting a much easier team (Titans). The rules will get changed because of that crap ruling, but it won't give us that game and possible SB back.
