Is potential draft position not relevant? Martone being a lock to go top 4 while the others all lasted into the late 20s/early 30s reflects the disparity between how scouts evaluated those guys in their draft years compared to Martone now, even if you account for differences in draft class quality. Martone making Team Canada in his draft year is also a strong signal he's in a completely different tier compared to Musty or Chernyshov. Then there's his offensive production which has also been much higher at the same age.
But my point is ultimately that if Hagens, Misa and Martone all hit their ceilings I would rather add Martone to Celebrini, Smith and Eklund than the other two.
