IMO, it should be battle between Suchánek and Hamrla for third GK spot. Even though we have some other good goalies who have some potential.
Honestly, I really doubt that there will be any other 04 defensemen beside Hamara. 02 guys like Kremláček, Talafa, Hrádek or even 03 guys like Machů are much more likely to participate.
For forwards, I like 04 group, but I still think that our only 04 forward in tournament will be Šapovaliv, he is the best of them and hopefully will get icetime for Kladno in Chance liga. 03 forward group is really weak, we will see what some of them will do in CHL (if it will start), but the other one who could be there is Brabenec. I don't think that guys like Koláček or Vrhel who play only in U-20 league will get the chance, even though Finnish U-20 has maybe more quality than Chance liga (but we will see how will they play next season).
Overall, next year team should have more offenive talent, primarly because more offensive d-core, but semifinals would probably be equal to miracle again.
