Let's take a look at what Bowman has done so far to the roster:
June 25
Oilers trade Evander Kane to the Vancouver Canucks for a fourth round pick in this year's draft. This increased the Oilers pick count to four from three. Although Bowman could've gotten more for Evander Kane than just a fourth round pick, he was more interested in the salary cap savings then the return of Kane, and because the player had a NTC he had to do him a favour and send him to his hometown Vancouver Canucks.
When healthy, Kane is one of the NHL's best power forwards and pests.
