Well, they're all competing in different weight classes, so they're in separate events. But, Akhil Kumar won gold in the last Commonwealth Games in the bantamweight division, Vijender won silver in the welterweight division, and Jitender won bronze in the flyweight division. So, they're capable of causing upsets. And they are our only medal hopes left, since Saina Nehwal lost in the quarterfinals after leading 11-5 (or something around that) in the final game of her badminton match.
