Character Analysis
The Irish national team triumphs in the Quidditch World Cup. Their Chasers, Troy, Mullet, and Moran, are much more skilled than the Bulgarian team's: "they [work] as a seamless team, their movements so well coordinated that they [appear] to be reading each other's minds" (8.92). They score over and over again. And their Keeper, Ryan, mostly prevents the Bulgarian team from scoring. (We don't hear much about their two Beaters, Quigley and Connolly.)
The Irish Seeker, Aidan Lynch, is another story. We're sure he's a perfectly fine Seeker, but he's nothing compared to Viktor Krum. And he also manages to plow into the ground not just once but twice in pursuit of the Snitch. By the end of the match, he's (unsurprisingly) dazed and "his eyes looked strangely unfocused" (8.154). But the Irish team still wins, so we're sure he doesn't mind the concussion.
