I think the Ducks can but won't be surprised if they didn't win the division. Like someone else said on these boards, the Pacific is a 2-horse race between the Ducks and Sharks with coming in a distant 3rd and fighting for a playoff spot late-season.
As for Dallas, they aren't going anywhere. They have little experience on the defense with only Karlis Skrastins and Stephane Robidas as their source of leadership. Tippett got them to play 5-man hockey while Crawford's more of an up-tempo system so, they'll be scoring a lot but also giving up a lot if Marty Turco doesn't stand on his head night-in and night-out, and who knows where Phoenix' gonna be playing next year.
Anyways, I think this year's gonna be a very close race with the Sharks barely edging over the Ducks by no more than 3 points. The Ducks will definitely be giving the Sharks all they can handle.
