Mike and Shane are probably two of the five best breakers in the world when a break box is in use, whether the "three balls rule" is used or not. Their chances go down if the break is from anywhere in the kitchen. Both are very experienced playing with a shot clock, and that's another plus.
Still, even a trip to the semis in this event takes really great play. International teams in recent memory that will offer a stiff test to anyone and everyone are: a) Philippines Orcullo and Van Cortezza ,b) Netherlands Feijen and Vandenberg, c) Taiwan Ko and Chang, d) England Appleton and Boyes, and e) Germany Hohmann and Souquet. Shane and Mike are capable of beating any of them, but can also lose to any of them.
This is the team that gives the USA it's best shot at the World Cup, and I wish them luck.
