There's also St-Denis who could be back if he doesn't make our team and we can squeeze him through waivers. He plays the right side.
St-Denis is a LD but can play on the right side, but they could also bring Mitera back even though he's a LD he would be a solid 6th or 7th D and has a couple years experience and should be a cheap contract. They could try and bring Callahan back if they need another vet although I don't think he will return he was solid for the Dogs and is a RD.
Good for him! Gotta check out new things in life, else you grow stale. Glad he his looking abroad for something new ... regardless of coin, or staying with one team: one life to live! Seize the day, YO!
