I think Radivojevic could be the Slovak Tomas Galvas, with fans and "public scouts" saying "HOW DID THIS GUY GO UNDRAFTED" while NHL teams just see a small D who can't skate. Svrcek could be in a somewhat similar boat as he, too, is a smaller guy without a truly high-end skill/sense combo. But I definitely like him as a bottom-six energy project at least.
Pobezal, Misiak, Straka are the players I'm probably most confident about. But I will say I probably don't watch these players as much as you guys.
