I just can't see the sabres getting a huge haul for a pending UFA goalie....sure miller had that great year a few years back, but Tim Thomas has won 2 Vezina's in the past 5 years and no contending team wanted him (even though they wouldn't lose any assets)
Maybe a Miller for MAF swap could work, but I think Buffalo would have to add to make up for the fact Miller is an upcoming free agent
