Police take statements from witnesses at crime scenes, and if the witness changes his story, they know he's not a credible witness. That video is from Total Access, the day after the game. As the host told him, "You've been looking at this all day long, so you've got your explanation down pat." Wink, wink.
Before Blandino had had a full day to prepare an explanation, when he was first interviewed by Eisen on
Game Day Final, he was specifically asked about the football move. He didn't say one word about the lunge.
"In order for it to be a football move, it’s got to be more obvious than that, reaching the ball out with both hands, extending it for the goal line. This is all part of in our view, all part of his momentum in going to the ground."
Who knows why he actually overturned the catch? An hour afterward, it was because the reach wasn't obvious enough. 24 hours later, it was because the lunge wasn't as good as a better lunge they'd found. In any case, he says all Dez did was fall. He has to say that, because if Dez did anything to advance the ball, by definition it's a football move and it completes the catch.
