I suggest you read the last 3 paras of the Guardian article. It is very clear from Manti's own words that the experience has had and continues to have a huge impact on his confidence on the football field. Yes, I would call that destroying what could have been for him
That may well be what he believes, but the simple fact is he was nowhere near good enough physically to warrant being drafted any higher than he was, and his shortcomings on the field itself are entirely down to his limited size and athletic ability. No amount of added confidence would overcome those.
The documentary states he was drafted far later than expected which potentially cost him millions of dollars and impacted his career
That's simply untrue.
I am a huge NFL fan, have been for decades. It was my team that drafted Te'o. They moved up in the draft to specifically to take him. At the time it was almost a universal opinion that the team had 'reached' for a player whose ability did not warrant drafting him that highly. As his career panned out, it was obvious they were correct. He didn't even earn a second contract with the team that drafted him, which is the single biggest indicator there is that they blew the pick, he didn't warrant the draft slot, and that he did not play to a level commensurate with the investment made in him.
He was ridiculed and mocked mercilessly. Teams didn’t want to draft him in case he was gay. And yet he has forgiveness in his heart where as the one that caused the chaos only considers their emergence from the chrysalis
Yes he was mocked, that's true, and there was some suggestion that some teams had blacklisted him over concerns about his sexuality, but my point was that despite all this, one team went ahead and drafted him at a spot where his talent didn't really merit the selection in any case, they were roundly criticised for this, not because of any off-field concerns, but because of the perception that the player didn't merit that on ability, and in the fullness of time the people who felt that the player was overhyped as a football player were proved true. He was given a chance over and above what his ability merited, and that came with being paid over and above what his production merited.
Manti Te'o still had a lucrative and reasonably lengthy career in the NFL despite the sideshow of his college days, but there's absolutely nothing whatsoever that suggests he'd have achieved anything above and beyond what he actually did achieve if the whole saga had never happened. He just wasn't physically capable of it, and he wasn't actually that talented in the first place.
