You do get this suscipion just from the history Russia has had with doping, including very recently. Was watching both their matches and feeling very happy with them playing so well (I have Russian roots, so follow them during big tournaments, as my other team is completely hopeless), but pretty much instantly started thinking... there's a good possibility they're doping, which dampens the mood.
There was one match, which is not yet in the table above, which teams had 'total distance covered' that is closer to Russia numbers:
112 km Australia - 114 km Denmark. Which is close enough to Russia's:

Czerczesow was Legia Warszawa's coach for a season or two, apart from Petrescu's Wisła Kraków, I have never seen a Polish team that would run so fecking much and always hassle their opponents. The players, as per usual, were complaining at the intensity of the training sessions and that Czerczesow's pretty much an authoritarian coach, but sure as hell it brought them rewards in winning Polish league.
So basically no, doubt they're doping, it's just that their squad is shite and Czerczesow gets the most out of it by running them to ground. And I hate Russia.
Good insight. That is pretty relevant I think. That's my favourite explanation so far, because I don't want to believe they're doping, even though it is likely are
And even if they did train harder than anyone, it still doesn't prove they're not doping, of course.
Now if they play badly vs Uruguay today, will it be more suspicious it they play well or not?
If they play well it's proof they're doped, if play badly then it's just because they heard of the suspicions and tanked the game on purpose. Just kidding
