Assuming Thomas is playing and this is short term, the Bruins duo. Real life Blues. Very confident in the Rask/Khudobin duo though. Khudobin is unproven, but has looked damn good in his few NHL appearances.
Tim Thomas, and Lundqvist weren't great in the all star game either. It's just a combination of things. never practiced together before, no real system at all, each line full of type players in the league, etc.
This season it would be Halak/Eliott, simply because Thomas is on his sabbatical. Going forward (which I interpret "as a GM" to mean), it's Thomas/Rask. Thomas will probably be good for 1 more season at a high level, and Rask is probably the best goalie going forward. Thomas doesn't have much value because of how little time he has left (I can't see him playing more than 1 season after he gets back from his year off), and Eliott is probably just a flash in the pan at the elite level. It basically boils down to Rask vs Halak going forward, because Thomas won't be around for long, and Eliott probably won't be elite for long, and I see Rask as a slightly better goalie than Halak going forward. Hard to go wrong with either pairing though.
Since the poll is going forward, obviously I take Halak/Elliot. Blah blah Hitchcock, if hitchcock's system and coaching are the same for the next 3-5yrs, without question it's Halak/Elliot. Even if it's not, Rask/Thomas isn't going to be a duo for long. Next time Tim Thomas is likely gonna touch nhl ice he's gonna be 39yrs old and have missed a whole season, or he could retire(he's weird and it wouldn't surprise me).
Better resume: Thomas/Rask without question
Who'd I rather have going forward: Halak/Elliot without question
