Hemsky has never done a good job of using his teammates. Yakupov is a shooter. If Hemsky chooses to dangle through 2 defenseman rather than move the puck, Yakupov isn't going to shoot. Hemsky is a contributing factor to Yakupov not generating offense at ES.
Right now the Oilers are Team Dangle. Hemsky, Hall, Eberle, Nugent-Hopkins, and Yakupov all try to dangle multiple d-men 2 or 3 times a gaime.
