Hawks have had more puck possession by a large margin and the chances/shots stats are lopsided. Howard dominating (see, this is where you can use the word) and the hawks hitting posts does not equal the Red Wings dominating...
Also the books are sharp and they are not going to overreact to the hawks losses to a really hot goalie, the first seed who has destroyed everything in its paths is not going get a major line adjustment vs a seventh seed. To further prove my point, you will see that even next game the Blackhawks will be a favourite -140 favourite (little bit less or more)
