Regardless of where you rank them, I take exception to this statement.
Slovakia has been able to participate in 3 Olympics in which they were able to send their best: Turin 2006, Vancouver 2010, Sochi 2014.
In Turin, Slovakia went 5-0-0 in the preliminary round, including ... a 3-0 win over Sweden...
Tre Kronor, as their coach ( BAG was it? ) tacitly admitted, live and on camera

, mailed it in, in one of the most shameful episodes in international hockey history...
Still a Win's a Win

EDIT: On paper I'd still put Russia at #2, in terms of star power...they're NOT well coached, and haven't been for years, they're philosophically bereft of new ideas/ stuck in Vik T era, can't make adjustments on the fly, eg: tend to be clueless when teams like Suomi take lead + play kitty bar the door, keep trotting out same line combos in succession, lack cohesion btwn D and forwards, lack guys like Toews or Bergeron who play a great 200 ft game, won't add dump and chase to their repertoire to back in/ turn opponents D when entering zone, attackers keep wanting to beat D one on one at the blue, leading to turnovers, counter attacks, yadda yadda
In a nut shell, Russians ( both individually and as a team ) can be esthetically pleasing , but frustrating too due to their collectively LOW HOCKEY IQ.

On paper, States and 3Kronor come next, pour moi. Tough to chose between the two, red white and blue have better depth, but haven't historically produced many top scorers for some strange reason?
