Had any of the top 6 teams (or probably even France/Brazil) had HCA, I don't think we'd be getting such an interesting, exciting u21 WC.
With one game left in round two:- 6 teams are still in the mix for the final 4.- 3 teams still have a chance at the top seed for the semi-finals.- There are a ton of crazy scenarios for how the final week will play out as all 6 top teams have a realistic chance at the title, and therefore have to weigh the effort options carefully.
At the same moment in last NT WC:- 5 teams had chance to win medal- 3 teams had chance to gain seed #1 before semis- at least 4 teams had realistic chance to win title (in current U21 WC, not more than 5 teams have realistic chance to win tournament, You made mistake in calculations).I don't see big difference ;-) Little differences are always possible because of schedule, strategy, mistakes of NT managers (e.g. China destroyed enthusiasm before first round of current U21 WC), good luck or bad luck (game shape, injuries), etc.
