I think trading down would be a good thing to look at, but I also think it's possible that a lot of teams view 7-15 pretty similarly so they wouldn't trade up that much to move up. I'd want to make sure I pull off someone like Kindel if I'm trading down, and I think you need to be picking above #20 for that to happen. I think the best opportunity for trading down would be if McQueen was still available and a team in the 16-20 range was sold on him and wanted to trade up for him.
In terms of mock draft, it's interesting that so many people are assuming that Martin is definitely going to be gone by the Penguins pick, while he's usually being mocked in the 10-13 range from most sources. He definitely feels like the kind of guy to get overdrafted, but purely in terms of mock drafts, he's not being mocked outside of their range:
-McKenzie: 12th
-Wheeler: 10th
-Pronman: 10th
-Elite Prospects: 18th
-Central Scouting: 11th ranked NA skater
His stock definitely feels like it's rising, but he's being pretty consistently mocked right in their area in the draft. I wouldn't bet on him lasting until #11, but he feels like someone that will probably be going in the #8-#10 range.
