Two Groups

This year seems different at the Tim Horton 2010 Brier. There are clearly (at least so far) two groups of teams. In the upper group, there's Ontario at 7-0, Nfld-Lab 6-1, and then Alberta, Northern Ontario, Manitoba, and Quebec all at 5-2.

In the lower group are Saskatchewan, New Brunswick, and BC all at 2-5; and then Nova Scotia, PEI, and the Territories at 1-6.

I don't recall having seen such a division into the two different groups at past major tournaments.
