Here are stats from the US group play; I stole them from the "other" forum.
Annie: 55 kills, .294, 4 blocks
Avery: 30 kills, .179, 2 aces, 3 blocks, 2.36 (74)
KP: 24 kills, .159, 3 aces, 5 blocks, 1.96 (69)
Chiaka: 23 kills, .425, 2 aces, 16 blocks
Haleigh: 19 kills, .361, 4 aces, 9 blocks
JT: 16 kills, .314
Kelsey: 5 kills, -.043, 1 block, 2.39 (42)
Larson: 4 kills, .000, 1 block, 2.19 (24)
JWO: 2.35 (48)
--Haleigh and Chicaka hitting pretty good from the middle.
--Only Annie Drews of the OHs, is hitting over .200 (pretty grim stat).
--Kathryn Plummer is receiving at under 2 clip (that's on a 0-3 range), didn't expect her to do good. Unfortunately my expectations were met.
--Kelsey and Larson both are hitting at or under .000 (which is why Plummer and Skinner came in for them in set 3 of the China match and started for them in the Serbis match.
--BUT, Kelsey and Larson came in for Plummer and Skinner in the match against France, cuz the serve receive for the two was pretty poor.
--JWO doesn't have the best serve receive numbers on the team, (by very little), but that is probably because she has been covering more court when Plummer is receiving.
This is sorta what I was expecting except that I thought Kelsey and Larson would be able to generate more points. They can't, so that's why Plummer and Skinner have replaced them. But Plummer and Skinner are prone to give up runs because they periodically run into receive problems.
The US doesn't have an ideal OH. They have good receive and no hit, or not so good receive and good hit. The US needs Plummer in because she can bomb the ball from anywhere. But she can be a liability at times on the serve receive. Oh well.
Someone suggested putting in Kelsey with Plummer as the two played together in a professional league, (in Italy I think), and won some championships. Karch hasn't tried that combo yet, not sure why.
With this somewhat flawed combo of OHs, IMHO, the US will have trouble beating the top 3-4 teams.
It looks like the US will play Poland in the quarter finals. Some people think that is good. From what I can see, the US hasn't done well against Poland; I guess we'll see.
The only team I would feel comfortable with is DOM, and they can also be dangerous, as, depending on the day, they can beat, (or lose to), anyone. Every team in the quarterfinals can be dangerous.
