By my count the Oilers now have 49 contracts. Adding Pajaarvi would make it 50 so I don't see that happening.
That's why they should grab Hackett.
Goaltending is a bigger need. Even if he isn't a starter, you guys know what you have in your current tandem. They both look like they've keeled over.
On Fraser:
He's been a very good AHL player, and about as prolific as you can get as a goal scorer in that league the last couple of years.
He's a grind it out, muck it up player with good hands around the net.
He's never found a role, never scored enough at the NHL level for a top 6 role, and isn't a checker. If he can be a net front guy, it gives the Oilers something more of what they lack and moves away from the soft skill wingers that don't show up every night.
That alone in itself is a win.
