NFL still trying to explain the wrong call makes it worse in their explanation.
See the bolded underline below and then tell me they made the right call.

NFL, Al Riveron continue to defend Jesse James' overturn
The NFL's VP of Officiating said that James did not "survive the ground" in his eyes and that's why the touchdown was overturned.

Jesse James did not "survive the ground" in his eyes and that's why the touchdown was overturned.
That's according to NFL VP Officiating Al Riveron, who ultimately made the decision to overturn James' touchdown on Sunday night. Riveron once again defended his decision during a conference call with the media on Thursday. 
“In this situation, it was not necessarily a football move,” Riveron said, via ProFootballTalk.com. “It was going to the ground. Any time you’re going to the ground, whether it’s on your own, whether you’re contacted by an opponent, or whether you’re contacted by a teammate, you must survive the ground.
"What does that mean? That means once you make initial contact with the ground, you must have control of the football before it touched the ground. In this situation, yes, his knee goes down. But we know Sunday football, the knee going down, you are still live and can do whatever you want with the football as opposed to college football. 
"So, yes, the knee was down, he does make another move where he’s reaching for pay dirt. Once he reaches for pay dirt, he loses control of the football. Before he regains control of the football, it touches the ground. Therefore, it was an incomplete pass. This is not so much about a football move, it’s about going to the ground. In the process of going to the ground, you must survive the ground via having control of the football upon the initial contact with the ground.”
While he continued to defend his decision, Riveron failed to answer the real question: Did he actually have enough evidence to overturn the call on the field? He had to have "indisputable evidence" that James did not cleanly possess the ball on his way to the ground, something that is still questionable given this photo of the play that emerged this week.

Here's my view/ photos of the "drop". Sure looks like his right hand was under the ball the whole time, but thats just my opinion. #itwasacatch

Riveron also needs to explain how he ruled this play involving Patriots' receiver Brandin Cooks a touchdown back in Week 4.

This is the Brandin Cooks "touchdown" that beat the Texans in the final seconds. Also here is the explanation for why Jesse James didn't score a touchdown. Something just doesn't add up here @NFL

It's clear that the NFL needs to give the Steelers and Steeler Nation more answers. It's also clear that, if they face New England again, Pittsburgh needs to beat them defiantly while not leaving the outcome of the game in the hands of the officials.
