"Sending him off while he still had something in the tank is a much more pleasing ending to the story than him being in his late 30's and a shell of himself that fans are begging to see removed from the team."
My instinct tells me that there's a good chance but just like his move away from Philly, his return also depends entirely on him. It's in GM Chuck Fletcher's best interest to not promise anything to Giroux or the fanbase.
