While not as big as either Shepard or Turner, Kathryn Westbeld was certainly not a guard.
ND had only 3 healthy scholarship guards most of last year, the same 3 that played all game today.
That being said, Westbeld was great for exactly what you mention. The team just flowed better with her in. She didn't necessarily get a ton of assists but she kept the offense moving. This team is still finding it's flow. Of course, it took last year's ND team a while to gel, too.
Meanwhile UConn's "flow" was excellent. If someone is out of position and scrambling to catch up, UConn is excellent at quickly finding the open man before the defense can recover.
