My general impressions:
Netherlands was the best team yesterday, there service decisions really helped block-defense by creating difficult situations for Glass. So much so I think Kiraly stayed in 5-1 because they had a difficult time scoring with first tempo in front of the setter. Unfortunately Grothues injury was more than meets the eye. Beside her stability in reception she also is a great and precise defensive player I think you will see how Sloetjes quality of attack in transition will diminish of Grothues is unable to come back.
USA has the best team but in my opinion 5-6th best coaching staff. I think in crisis Kiraly (and staff that includes Dunphy) does not have experience to recognize some strategic aspects that change throughout the match and cannot respond so I think it will be up to the players to navigate problems. I don't think encouraging them to celebrate or breathe deeply (or insert cliche here) after lost points is enough to bring the team back from deficit and unfortunately I think the players realize this. I don't like arrogant posturing and I think Americans are know for this but what I saw yesterday was arrogance quickly turn into panic and I am convinced they escaped with victory because of misfortune of Netherlands.
I think Kiraly also second guessing decision to bring the players such as Thompson and Lowe perhaps instead of Fawcett and another multi-faceted player in place of Thompson. Serbia has type of service attack and block to create problems for USA.
I would argue Netherlands was playing the best level of all teams until the injury. Brazil is difficult to tell because they are pacing themselves against Cameroon and Argentina.
