Again, Marek Hrivik for proving as a 20 year old that he's capable of playing on the AHL first line. The Rangers already indicated that he's likely to be the first of our prospects (besides Hageline and Kreider) to get called up to the end.
Add Sam Noreau, he's having a good season. Big fists, decent mobility and now he's showing some flashes of being able to chip in a little bit offensively. He's got real potential to be a tough top-6 defenseman.
Between Oscar and Marek both have shown capability to play at a very high level. Marek is doing it here in NA which is a major plus so I can understand giving him the edge. I don't know Marek's defensive game though everyone raves about Lindberg's so if Oscar's D is really that good and Marek's hasn't been worth mentioning (Maybe solid but unspectacular) I'd give the edge to OL
