I think it makes little sense that the games overview is player-based, as is now. These are duels between teams, one wants to to see the scorecounting, the games within these duels.
There could be a crosstab, like the one for individual tournaments. But here instead of a result, a cell could give the scored points in the different clan duels.
The drill down should give a list of the games between the 2 clans.
Then one could see how the clan is doing versus each specific other clan, the direct rivals in particular.
