There's corruption at a really huge rate when we look at the committee of the Olympics itself and for them to ban Russia now I think it's because it's already becoming too much. These guys are cheaters from day one always looking for technology to improve everything.
They should be handing out life time bans to any athlete caught cheating. Technology needs to change and catch up otherwise as a sport it is finished.
The beauty of the game will just die because of cheating
