IMHO it's too much of our future to give up. Granted, you probably have to overpay to get Burrows included. But I don't think we need to overpay that much. Plus I don't see why they'd have an interest in Halak at all. They have Schneider who seems to be just as hot as Halak in the AHL and just as ready for an NHL chance.
Ohlund would be a nice pickup, but again, I think we're a couple months away from finding out which impending-UFAs really are going to be available for us to acquire. They can't afford to deal him now. And if they're in a solid playoff spot, which I expect they will be, they'd be smarter just to keep him this season and then let him walk in the summer.
