Great article.
Definitely not tasteless, but definitely offensive for some. But most Onion parodies are offensive to someone. News parody that doesn't get someone riled up isn't doing a good job.
Making someone who is making millions of dollars but is injured hardly seems unethical to me. He is still an NBA player. He still has a bright future either in the NBA or investing his money post NBA. Oden is not someone who needs to be protected.
I find the 'old man' jokes far more offensive than the injury prone ones.
