I think Wog did well enough to be selected for the final. Nicol won't do much better (and is probably not mentally prepared to race), but they could slip in Angus if she showed improvement in training during the week though if she did, they probably would have tested her out in the heats.
Canada really needs to improve their breaststroke swimmers for both the men's and women's, our medley relays suffer a great deal. The don't even have to be threatening for an individual medal. A woman who can consistently dip under 1:07 would make Canada a gold medal contender in the relay.
