The question is who would go 2 instead? Misa only had 75 and he doesn't play the same type of power forward game as Martone can play. McQueen has intriguing upside, but only had 51 (in 53 games).
Frondell is a candidate. Ryabkin would be another. Aside from these 6 (Hagens, Martone, Misa, McQueen, Frondell, Ryabkin), it's tough to find top 5 candidates. Someone will surprise next year. At least one always does, but I think Martone has the best case right now to compete with Hagens. Needs to score like 100+ points next year, makes the WJC team and do well there, but I think he's a good candidate for all of that.
