The Sabres would like to upgrade their center position, and get bigger up the middle, and are expected to package Roy as part of a deal.
TFP reported this past week that the Anaheim Ducks could entertain offers for center Ryan Getzlaf, and several teams are expected to make inquiries about his availability.
It's uncertain if the Ducks would consider Roy as part of a package for Getzlaf, but it would not come as a surprise if Regier makes a few calls to Anaheim GM Bob Murray.
The Sabres also have a surplus of defenseman and could either include one in a deal with Roy, or complete a separate deal and swap one of their blueliners for some depth up front.
