Dropping Hiller seems to be the only valid and logical player to drop, even considering your bias.
Corey Perry and Ryan Getzlaf I don't have to convince you to keep.
Tim Thomas was the Vezina, Conn Smythe and Stanley Cup winning goaltender this past season. There is no way you can drop him. Even if you're not crazy about him, his trade value is just astronomical.
Giroux is what the Flyers believe is the new face of their franchise after clearing out Carter and Richards. Look for his numbers to improve as his responsibilities to the team have as well. His +/- should go up as well with the signing of Bryzgalov.
Doughty is an elite defensive option with huge upside on an up and coming team. There are few options as strong as him.
Hiller played 49 games last season and only 14 in 2011. He would be the easiest to re-draft and although he is a great goaltender, is his future clear considering health issues and uncertainty?
I would drop Hiller. No questions about it.
