The biggest issue most folks hold against Manti is the belief that when he found out on December 6, 2012 Lennay Kekua died, he didn't inform the public. He continued to use the tragedy of her death from cancer for self-promotion. This 21-year old football player was able to play in spite of his grief; in fact he channeled it in on the field and off of it.
Katie Couric went after Manti for this as we knew she would. She showed the video clip of Manti speaking after the Heisman trophy award ceremony and said "your repeated the story that your girlfriend had in fact died of cancer. Let's listen..."
Manti: I don't like Cancer at all. I lost both my grandparent and my girlfriend to it.
Katie: That's a lie, why did you say that?
Manti: At that time, I didn't know. To be honest, I didn't know that.
Katie: C'mon. This person calls and says it's Lennay. (With a very strong tone of voice) You stuck to the script. You know something was amiss Manti. Why?
In this instance, you may default to another virtue like kindness rather than honesty and say "I'm so happy to see you tonight." They get it.
For Manti to reveal to the public that he had been duped or explain that a woman he had been exclusively involved with from April 26-September 12 (we are talking about a 4-month relationship people) was now alive would not have been prudent. To take away from the actual winner of the Heisman with his weird and unbelievable story would not have been wise. He could speak in the way he did with integrity--which was his defense. Their deaths to cancer were real to me, Katie.
