I don't think Poland has a big chance to qualify to the Olympic Games in London. Their World Ranking is lower than Germany,Serbia and Russia. So, The European Qualification Tonurment is the only chance They can get the ticket. I'm not quite sure What Swiderek thinks about it now...
Setters : Milena Radecka, Katarzyna Skorupa
OPPs : Katarzyna Skowronska-Dolata, Natalia Bamber-Laskowska,
OHs : Anna Werblinska, Kinga Kasprzak, Elizabeta Skowronska, Anna Podolec, Karolina Kosek, Anita Kwiatkowska
MBs : Agnieszka Bednarek-Kasza, Katarzyna Gajgal, Berenika Okuniewska, Gabriela Wojtowicz
Liberos : Paulina Maj, Mariola Zenik
I think This roster looks very strong, Although Glinka is out...(I heard She wants to retire after this season, so Glinka playing in NT doesn't seem possible at the moment...)
It's indeed very difficult to choose OHs apart from Werblinska. Kasprzak is unhealthy very often, E.Skowronska doesn't want to play in NT as far as I know, Podolec...I don't know If she can still play as OH, Kosek, Personally I don't really think She deserves to be play in NT and Kwiatkowska plays as OPP usually...
I have no idea actually Werblinska-Kasprzak duo seems the strongest OH line-up Poland could ever make for now.
About Setters...Skorupa obviously should be back to the Team. Radecka is a great setter IMO, but sometimes her sets are extremely predictable. besides She is playing absolutely well in Italy. Asia Wolosz can be a good choice too, but I prefer Skorupa as main setter.
OPPs... Kaczor doesn't seem in great shape, so I'd rather beg to Bamber. She can absolutely be useful, since She can play any position.
MBs... It's very obvious. Wojtowicz can be a fantastic choice. I know She doesn't have any technics, but her height may be very useful as well.
Liberos...no doubt.
