It would be great to have Kurek in Serie A. Most importantly it would be very good for him. He would gain a lot thanks to Serie A. He would improve a lot in Italy. Unfortunately he signed new contract with Skra and he'll play here till 2014

... if I'm correct. He would get a real volleyball lesson in Italy
I have nothing against Kurek's staying in PlusLiga. He is young and has time to play in Italy. He can also improve in Polish league, which is good enough ( it is not football league). It is better to stay in Poland than go to Italy and be a substitute in some very good Italian team or to be first 6 player in an average team (like Bartman e.g.) . Of course, right now Kurek is also a substitute quite often, but I think it will change very soon.
Some years ago all the best Polish players were leaving Poland and were playing in Italy or Russia. Now we have another direction - Poles are coming back to Poland.
Kurek in Skra till 2014? Why not?. It means, this team still wants to be good and cares about Kurek's ( and some other players') future. He is able to improve also in Skra - playing in playoffs in PlusLiga or in Champions League.
