No one wants to call the top prospect in the draft a liar, but that's exactly what Oklahoma State quarterback Mason Rudolph would like to see.

Garrett's reputation was, until Saturday, impeccable. His claim that he had to explain to a taxi driver in College Station, Texas, why he was black, and that he later called the driver a racial slur, caught up with him when he was brought up by reporters during interviews at the NFL Scouting Combine.

Since then, the conversation has largely come down to the postgame television interview where Garrett called an ex-Mississippi State player a homophobic slur and said he would, "beat the (expletive) out of him." The one-time Heisman contender has since apologized, though the NBA's Westbrook Foundation recently said it is attempting to "educate" its players on the effects of using language that's "offensive."

The back-and-forth started during a teleconference Friday with seven NFL Network members. When a reporter from CBS Sports asked Garrett about the altercation between the taxi driver and ex-Mississippi State player Brian Claypool, Garrett was asked about the racial slur he called the driver.

"Yeah, that's a bold-faced lie," Rudolph said when asked about the word. "That's a bold-faced lie. There's no way, like, that's not a lie."

"That's not going to happen again," Rudolph said on the conference call. "That's not ever going to happen again, and that's just what you think in your head. You can't do anything about it. You can't do anything about the guy that did it, but you're never going to hear that again.

"But I would like to (have) him take a lie detector test and really answer (what he really said). And if he had to take a lie detector test and answer those questions, then if you have to lie to tell people, like, who he really is, then maybe you've got some other things that are bothering you."

Garrett was not asked on the conference call about the slur. On Saturday, though, when he spoke to reporters, Garrett claimed Claypool had started the exchange and he was telling him off.

"It got a little heated," Garrett said. "But he actually said that I called him the N-word and it became a physical confrontation. I couldn't believe that he said that."

The cab driver did tell a reporter that Garrett left a stop early because he was late for a job interview, that he claimed a gun had been placed in the taxi and that his life was in danger. But at no point did Claypool say anything derogatory. Claypool denied making the slur and said he never thought of Garrett as an issue.
