"It would be fair to characterize that I'm actively finding out what the marketplace is like," Regier said, "and it's not limited to those two players."
Sources have told TFP that neither Miller nor Vanek will sign extensions with the Sabres, prompting trade speculation.
Regier indicated that he's had some talk with both of their agents, but they're exploring all of their options at the moment.
The goalie market has changed in the last few days, with Vancouver trading Cory Schneider to New Jersey, the New York Islanders buying out Rick DiPietro and free agent Tim Thomas jumping back in the mix, Regier admitted that he's "not sure" how it will affect the value of Miller.
With the NHL Draft now a thing of the past, and free agency creeping up, Regier said the trade market is "forming a little more."
Several teams are expected to make more moves this week and next, and that should make things very interesting for the Sabres and their future.
Meanwhile, Regier plans on exploring the free agent market, but might not go after some of the bigger names that are available.
"The focus is going to be on supporting this younger core group," he said. "Certainly, you want good players, but you want players that are committed to being examples, being contributors."
