I just watched the play. Catch and touchdown. Do doubt.
And I dislike both teams.
See the explanation above at #189...there were actually two reasons (explanation from the NFL) why it wasn’t ruled a catch. When you watch the replay, it is true...the guy is in the process of going to the ground as he crosses the goal line.
According to the NFL, he was still in the “catching mode” because you have to complete it down to contact with the ground and he didn’t do that.
I wouldn’t like it much either if I were rooting for Pittsburgh, but that is the rule. Like many, I believe they should change the rule to something simpler, but that is what the rule is right now.
It was neither, by the rules that all the teams play by. The ball moved when he landed, before he established possession, so it was not a catch. No catch means no touchdown.
