Here’s the real story: Manti Te’o’s stock in the NFL draft already was sinking.

Blame his performance in the BCS title game, not any hoax or conspiracy, for that.

Still, the uncertainty surrounding Notre Dame’s All-American linebacker could further hurt his draft stock, NFL draft consultant Gil Brandt said.

Brandt called the story "something I have never witnessed" in his half-century in pro football.

"I think some teams will say it isn’t worth the problem" to draft Te’o, said Brandt, who has the linebacker rated 19th overall in the first round.

The former Dallas Cowboys general manager added Thursday that Te’o’s stock had plummeted after a poor performance in the BCS championship game.

"I don’t think anybody considered him to be a top-five pick before all this happened," Brandt said. "In that game against Alabama, this was like a guy who was the best shooter in the world in basketball and here comes a game and he can’t even hit the backboard. His play in that game was absolutely horrible. He missed on run blitzes; guys ran over him …"

Te’o would hardly be the first player to see his draft stock sink because of off-field issues. Last year, North Alabama cornerback Janoris Jenkins fell to the second round after multiple run-ins with the law related to marijuana got him dismissed from Florida.

Warren Sapp in 1995 and Randy Moss in 1998 slid because of character concerns; both are now considered potential Hall of Famers.

Chicago Bears general manager Phil Emery said "it’s no different what the red flags are."

"You’ve got to identify them," he said. "You’ve got to research it and then you decide what impact that has on the total person in terms of his ability to play football and to manage his life."
