Anyone that says this is an overpayment hasn't seen Reilly play recently. With a sound defensive partner he is great. Ottawa loses this trade easily. Should have resigned the guy for at least a season or two. That third has such a low chance of making it to the NHL Good move Boston.
He had Zub who was a pretty sound defensive partner. Not amazing but making him look good.
They have Chabot/Sanderson/Brannstrom in the future on the left side.
