With the star player rule eliminated for this year's tournament, significant pressure was put on teams to perform at a high level with barely any "star" performers. The two teams that did the best? Norway and Nigeria - the only two playoff teams without a majority of players in Division 2 or higher.
Since I'm unfamiliar with Nigeria's roster I'll focus on Norway. Plus, this is a Norway blog.
Norway had only three star players on its roster: Stefan Husdal, Reis Cooper and Andrew Baulin, and Reis was out for the tourny after Norway's second game. The remainder of the players came from lower divisions or, in the case of FIVE players, do not play at all besides the WCP Cup.
How did Norway do so well against teams like Jamaica, El Salvador and France? Good team chemistry and a lack of ego mostly. Norway doesn't have a coach and everyone gets equal playing time. The only way that can work and a team can be successful is if there are 0 losers playing for the squad.
I'm not going to fault teams for stacking up on star players because of course that is the best recipe for success. However, all the weaker teams in the tournament should keep in mind that you can still have success without great players - just figure out how to keep the idiots off of your squad.
