If Muel and Stillman can't go I'd call up whoever is next in line on D from Rochester to take Bryson's spot. Just a big body who doesn't get knocked down at first contact would be an improvement.
Edmonton has the #1 power play in the league and it's not really close. So after Monday, if the Sabres don't stay out of the box, they may be back to 32nd on the PK.
