In the case of Shaw, his partner, Elliot Sanderson, never got to attempt to pocket a ball, so I don't see how you draw this conclusion. They ran into a team that was in dead stroke. Hey, it happens.I think, what we saw today is, that Shaw, Albin and Grabe are not real leaders when it comes to doubles play.
In the case of Albin, he's a two-time winner of this event, so maybe he has what it takes to lead a partner to the finish line.
Not sure what to say about Grabe. He was so far off in his execution today that he had to focus primarily on his own woes. When the better player in a pair doesn't lead by example, it's always hard on the weaker player of the pair.
