Well, you don't need to worry about the Russians for a while, because they have withdrawn their whole team, due to being 100% doped on meldonium and other crap. I want Russia to be banned for the next 10 years from all sports all over the world and that includes tennis. They are a total disgrace to sports and civilization and more so: they spoil it for the real athletes!! What's the pleasure in getting any kind of medal so many years after you performed in a sport when you think you have been beating fair and square by another athlete or that you almost certainly know you've been beaten by dopeheads while performing?
There's so much cheating and doping AND corrupt checking on doping going on, it's hard to trust anyone anymore and you start to mistrust any decent/good/fantastic performance. In other words: it's very hard to really enjoy most sports. Goodness me, there are also plenty of countries who cheat and are using doping in the paralympic sports......for what exactly? So you can say: "we are the best in the world in disabled volleyball!!!!". while cheating by using abled volleyballers? (Iran/Spain). Wow, what a great wonderful, honourable feeling that must be!!!!
My advice: once caught, give them a ban for life and a hefty fine depending on what sport. The more you can earn, the bigger the fine! Is it common in one country, ban the country for a painful period, let's say 2-4 years. Caught twice, ban them for even longer periods with big fines.
And for goodness sake, stop all these changes in nationalities. They are mercenaries (99%) and do it just for money. All these Africans that are bought by Arab states so they can buy medals, because they are too lazy, stupid or whatever to sport themselves. Also, quite a few European countries do it with Abeba Aregawi (Ethiopia-Sweden) being one of the most blatant examples. And now it turns out, she's doped to her rafters as well.
One of the few athletes I still really enjoy is our Dafne Schippers, but even as I think she doesn't do doping, I would not put my hand in the fire for any athlete anymore, certainly not when money is involved. It's really sad that it all had to come to this. I can't think of any Italian major cyclist who has not been caught doping the last twenty years and the saddest thing is that some (like di Luca) imbeciles has no regrets whatsoever to deprive other and better cyclists from glory, honourable mentions, history and yes, money.
Anyway, Dafne Schippers, our Dutch athletic hope since last year, has opened her outdoor season with a 22.25 on the 200m in very wet and windy conditions in Gainesville, USA. Last year she opened with 22.63 while still performing heptathlon till May. I am so very curious and a bit exited if she's going to run even better times than last year, especially while concentrating on sprinting solely this olympic year. And she made our 4x100 relay also a lot better!
´dance me to your beauty with a burning violin,
lift me like an olive branch and be my homeward dove,
raise a tent of shelter now, though every thread is torn,
we're both of us beneath our love, we're both of us above, dance me till the end of love´
