Unfortunately when you start to look at things like that instead of looking at the players abilities it starts to get misleading and you start to overrate/underrate prospects based on things that they simply do not control. Almost like saying that Weber is a better player than Subban because Weber was playing top pair on Team Canada while Subban was left out on most nights. There are so many things that come into play here that it cannot be simplified as you just did. The coaching staff and management of the WJC teams make these selections based on many things, including style of play they are trying to achieve, maturity level of player, is that player adding a different element that other players do not add? and etc etc. Sometimes it can legitimately just be a preference thing by the management and coaching, for example Phil Kessel not making team USA while he's one of the best players in the world under pressure, or Marty St-Louis not making team Canada years back.
Bowers and Norris are clearly in the same tier of prospects and likely that both turn out to have similar impacts on an NHL roster IF everything goes right and their development is good. When you start comparing players by who got chosen to this event and who did not, you're doing it wrong.
