Joey's record is very easy to find. It took me ten seconds. He has not had "eight fights in eight years." His pro debut was on June 16, 2000, against Miguel Angel Lopez.
A paucity of fights does not indicate that the fighter concerned has not experienced managerial or promotional limitations, as you suggest. Quite the opposite.
I would sincerely hope that most of his fights have been against fighters with losing records. After eight fights, he certainly shouldn't be fighting too many experienced, good fighters. Prior to Jimmy Lange, his previous three opponents all had winning records, but two of them had just three and two fights in total.
If you want to complain about a fighter on the show with a dubious record, I'd suggest you turn your attention to Juan De La Rosa, whose untraceable record was the subject of an earlier thread.
Your theory that Joey will throw challenges to avoid fights makes no sense. If, in the second round, challenge winners get to pick their opponents, it makes much more sense for him to win, if he can, so he can pick his opponent. He can't go far in the competition by not fighting. Not fighting is not an option.
Of course he won't win. He has nothing like the ability required to win. I would argue that, of the original 16, only four had a realistic chance of winning: Manfredo, Mora, Smith, and Kaddour. And indeed, available information suggests that it is indeed two of those who meet in the final. It was never a secret that the fighters wee picked, not just on their ablity, but on out-of-ring attributes. This isn't the NCAA. Its a reality show.
As I mentioned in an earlier thread, the producers had hoped to procure a higher calibre of talent (Ishe specifically mentioned Sam Soliman to me) but were unable to secure their release from their promoters.
