and russia lost its appeal with the board of arbitration yesterday on its track and field team for entry in rio.

they have maybe 1 more shot but i doubt they are going to be let in.

i would really like the rules change by wada to be:

1st time offense, you are out of all competitions until the end of the next olympics. ie anywhere from just a few weeks to 4 years.
2nd time offense, you are out of all competitions until the end of the olympics after the next. ie. anywhere from 4 years plus a few weeks to 8 years
3rd offense, you are banned not only from competition for life but you cannot be associated with any team at any level nor can you be an official in any capacity.
