His skating looks OK to me. As someone above said, not bad, just the weakest part of his toolkit, though I would also wonder about his offensive creativity. Since that is an intangible, it's hard to measure. Having said all that, I'm hoping my team runs up to the virtual podium to pick him at #11 if he's still there. MN needs functioning C's, especially ones that have a chance to be top 6 C's.
If he turns out to be another JEE? I can live with that, though I'd obviously hope for more offense. Having two JEE's is not the worst thing in the world.
