Yak is good in his own end, and hard to play against.
He is all of that, but outside of D zone starts it's hard to deploy Yakemchuk as a shutdown D-man because he gets walked on the rush. With his back skating and pivots, that issue might persist.
I don't think a team can take him if they don't have plans for him to QB the PP someday, that's where a lot of the value is.
Zayne Parekh has that same issue.
If Parekh and Yakemchuk are on the board at 10, they are very likely still on the board at 12, because New Jersey and Buffalo don't have room for more young D. Certainly not room for more offensive young D.
If Iginla and Sennecke aren't available, and if those clubs don't trade the pick, I'd expect them to go for a strong forward like Brandsegg-Nygard.
