We don't dominate:
Soccer (okay, we used to dominate Women's soccer. We'll see if this year's team can get back to that)
Rugby
Badminton
Field Hockey
Beach Volleyball (we used to, not anymore)
Canoeing
Rowing
Sailing
Handball
Water Polo
Yes, we still usually dominate basketball, but that's about it and it's only worth 4 total medals (and we only dominate 5v5, not 3v3).
