Stone, 26, is a five-time 20-goal scorer and has 311 points (123 goals, 188 assists) in 366 games with the Senators after being their sixth-round pick (No. 178) in 2010.
Dzingel, 26, has scored at least 20 goals in back-to-back seasons and has 126 points (62 goals, 64 assists) in 247 games with the Senators. He was their seventh-round pick (No. 204) in 2011.
Ottawa could possibly have moved its top three goal scorers by the Deadline in Stone (28), Duchene (27) and Dzingel (22). But Dorion is urging the Senators fan base to trust that they're headed in the right direction.
"It's part of the process of the rebuild," Dorion said. "All we're asking is our fans to be patient, and we have to respect the player's right that it's their right through the CBA that they can be free agents. And in Matt's case, that was his choice.
"We have to do what's best for the organization. At times it's a bit more difficult, but we know at the end of the day we're making the right decision."
