USA gymnast McKayla Maroney showed extremely poor sportsmanship after finishing second in Sunday's vault final. I know she had to be extremely disapppointed with the silver, since she was such a huge favorite. But she was way off base by basically, mostly refusing congratulations from the gold medal winner and the other gymnasts. She came off as a spoiled brat, for which I'm glad she lost. We certainly don't need more little sore losers in the world.
