In Gryba, the Oilers land a physical depth defenseman who shoots right--something they needed. He essentially replaces Martin Marincin on the roster, since the latter was traded earlier. Gryba brings more of a physical element than Marincin.

For the Senators, trading a defenseman was important since they had eight NHL-caliber rearguards. They landed a pick that the Oilers had acquired in the Marincin trade, plus an organizational depth winger in Ewanyk.

Gryba and Ewanyk don't have much in the way of fantasy value, as they are depth/role players.
