Gehan was the biggest offensive threat on this team up until her injury. Not sure if the slower set suits her beter since she hits so hard but she was, as the poster said above "the one" this year.
Murrey was still the biggest offensive threat. Gehan had a higher efficiency, but part of it was because the opposing defenses were putting up a double block against Murrey almost every time, and because they were worried about Murrey attacking from the back row.
Murrey is generally a craftier player, while Gehan tended to bring on the heat. I think that was a nice combination to have, but Murrey is going to struggle a bit until the sets are more to her liking.
