actually if you read the rulke they called it right. It was called an interception on the field and overturned by replay. The rule states, "for it to be a catch when going to the ground you must retain possesion all the way through the catch." Im paraphrasing but he didnt maintain possession all the way though the catch after going to the ground.
Not sure if we are talking about the same play. I watched the post-game news, and everyone said they botched the play where an interception by Pittsburg was rulled null, even though 100% of the commentators agreed it was an interception.
This is just a little of what has been said in the newspapers about this today. If you do a search, there are dozens of stories about it. I don't think it is settled at all, and had the Steelers lost, it would have been an incredible controversy:
It doesnt matter what commentators that dont know the rules say. All they need to do is open the official Rule Book and read the little note underwhat defines a catch.
If you want to know what the rule is watch NFL Network channel 212 on directtv on wendsday. The head officiating will be on like he always after ever week to explain calls, this call was explained lastweek. Tampa bay Non-called TD by Chris Simms same thing
