I'll go the other way on this one and take Doan. If it's short term and you can go back and grab Doan later than I'd consider Hanzal.
I like Doan's durability. Hanzal has played 64 and 61 games the last couple of years. He's already missed 4 games this year.
Doan is on pace to produce alot of shots and hits this year. Hanzal appears to have brought it all together but I'd be weary of his shooting %. Very high and likely to come down. If he's not injured first.
