I don't think Piechocki is too bad. Zatorski was not superb a couple years ago but he has grown into a reliable member on the court. I believe Piechu may become a similarly good player in the future.
Also, it doesn't make sense that Skra let Zati go because of Piechu because they could just keep both of them instead of taking Ferdinand. Unless there's some other stories...
I'm worried about Skra's next season. So far the starting lineup is still not too bad, but the bench players are way less competent compared to other top teams. I really wish to hear some exciting transfers later on.
And no. Skrimov doesn't fit in Skra. Skra needs, like many other teams, another Winiarski to keep functioning.
