NBC missed the mark in its coverage of Matthew Mitcham's gold-medal performance at the Olympics on Saturday, shying away from even mentioning that the Australian diver is gay. It was a pretty clear part of his story -- his boyfriend Lachlan Fletcher was in the stands and played a large role in getting Mitcham to return to the sport. NBC mentioned his "personal problems" on air, but failed to offer details. This from the same network that included all the details of Mitcham's coming out in his bio on the network's Olympics web site. When criticized for their sloppy coverage, NBC argued that they had done nothing wrong.
