After refusing to answer a postgame question about the the ill-fated blitz that led to the Jets’ 17-13 loss to the Broncos, head coach Rex Ryan admitted Friday it was a mistake.

“Hindsight behind 20-20, obviously, we would’ve done something, anything but that,” Ryan said of the decision to blitz, according to The Associated Press. “I even told the defense before (the play), ‘This kid is not going to take the ball out of his hand. He is going to keep it in his hand,’ and that’s exactly what he did. He ended up just making a great play. None of us saw it coming.”

On third-and-4 from the Jets 20, “This kid” — Broncos quarterback Tim Tebow — spotted the Jets dialing up their first all-out blitz of the night. Tebow took the snap, got past safety Eric Smith, cut back and rumbled into the end zone.

Ryan was asked about the call by The Post’s Brian Costello in the postgame press conference but the coach said he would not answer.
