Battle between Norway and Russia in men's XC skiing, and Norway vs Sweden in the women's XC skiing reminds me a lot of the F1 battle between Mercedes and Ferrari in the recent years. Not only does Norway (Mercedes) have the stronger squad, but they keep winning the tactical battle as well. On an odd they when things don't go as smooth they'll make a mistake, but most of the time the mistakes are made by their opponents .
Just look at the Ustyugov example: they kept pressuring him to run the sprint, telling him that he can go home if doesn't run it etc... all it did was exaggerate his injury, eliminate him from the Team Sprint which was a far better race for them and the 15km where I think he really could've medaled and potentially giving him long term injury problems.
Now they put Retyvikh in the second leg with Bolshunov, additionally tiring Bolle in a pointless run for bronze medal at best! They don't put Spitsov in the skiathlon, but put an old guy Belov well past his prime who performed mediocre at best in the skating this season just because they have 3 groups and every group needs to be represented in a race. Just keep shooting themselves in the foot constantly.
EDIT: FIS did it again, men's Giant Slalom and Team Sprint collide, and once again Eurosport will broadcast the all important Giant Slalom race where you know Pinturault all but won both the small Crystal Globe in that discipline and an overall big Crystal Globe.
P.S. Speaking of F1, team USA surely looks really strong tomorrow - Schumacher and Hamilton.
