Iverson seemed genuine to me in this video, and quite moving.
It's true that he usually gets the blame on everything but maybe he should also accept the reality, which is that he has past his prime and that coaches and managers seem him mostly as a cancer. Maybe this reputation is unfair but it's certainly not by saying that he prefers to retire if some team offers him a backup role that he will prove the haters wrong, and show his true value to a team.
