I'd be interested in giving Yak a shot on the Flames, but a 2nd + Kylington is way too much. I wouldn't even do a 2nd + Wideman, with nothing retained. Wideman will likely be worth a late 2nd at the deadline to a contender looking for a RHD who specializes on the PP. I'd offer Wideman for Yak. But if we have to retain salary at all, I'd offer nothing more. If we retain nothing at all, I'd add a 3rd.
So...
Wideman + 3rd '17 for Yak
or
Wideman (~$1.5m-$2m retained) for Yak
I actually think Wideman would thrive in Edmonton so I'm hesitant to even offer that. And if they chose to, the Oilers should have no trouble moving him for a late 2nd at the deadline. (Without retention), that gives the Oilers a late 2nd + a 3rd for Yak, which is above market value apparently.
