No, he's not objectively faster, but he's definitely better than some of the guys we have right now who would be competing for the 6D spot, and can PK decently well. Considering that we had Warsofsky and Siemens playing important minutes down the stretch, and guys like Timmins and Meloche are still probably a year or two away from the NHL, a short term band-aid like Cole makes sense. He was also a UFA, so we didn't give up any youth to get him.
Stepan, on the other hand, would cost us Compher, Kamanev/Meloche, our 1st this year (which could still be a lottery pick), and Ottawa's 3rd, if the proposal comes true. That's a lot of young talent going out the door for a 28 year old, with 3 years left on his contract. Then what's the plan? Would we plan on extending him into his 30s? Trade him after 2 years so we don't lose him for nothing as a UFA? Expose him in the Seattle expansion draft? I don't really like any of those options, so I'm hoping someone has a creative way in which this trade doesn't screw us in the long run.
