It is kind of interesting that there has been 0 news about Isaac Humphries for the last 3 months or so. His season ended, I assume he finished the school year out at La Lumiere, then he headed back home to Australia and fell off the radar. That's a situation that lends itself to speculation.
One note about him, if someone else hasn't mentioned- if he does come for 15-16, he has to be a multi-year player, because he just misses the age cut-off. He won't turn 19 until January of 2017, meaning he's not eligible for the 2016 draft.
