You know Tonga have some great players.
Taumalolo, Taukeiaho, Fifita, Fanua-Blake, Pangai are world class and would be picked for any team if available.
But they had a large contingent of players who are good, but played out of their skins. Guys like Murdoch-Masila, Staggs, Jennings, Tupou, Katoa, Hopoate, Hurrell, were all as good as anyone on the field.
Munster and DCE lack the game management of Thurston or Cronk (DCE has been injured all year though), so if it becomes a shootout between individuals Tonga have enough great players, and the rest playing out of their skins, to win that. Aussies needed to use team play, game management, and percentage plays to win, but had too many cowboys not willing to play that way, and only one individual (Haas) able to stand up to the brilliant Tongan individuals.
