I was wondering about Andalucía-Caja Granada since they have a Vuelta invite and have done absolutely nothing to merit it.
As for the Russian Nordic skiers, yes, lots of suspicion there, plenty of convenient timing (where did Elena Khrustaleva - who has represented Russia, Belarus and Kazakhstan - suddenly get those Olympic showings from? Or how about Maxim Maksimov, who has 3 top 5s and 2 podiums in his career, and all of them have been in the World Championships?), but ultimately that's a story for the XC thread (and my examples, as usual, are biathletes, where it's less obvious I guess since things like beta blockers come into it too for the shooting).
