From the Canes standpoint, this feels like a setup to something bigger.
Yes, this adds a RH D to the pipeline that we are lacking, but man, our pipeline is loaded on defense, and this only made that situation worse. Even if we lose TVR and Edmundson this offseason, we're still looking at filling that last roster spot with Bean, Priskie, or now Keane. And after Hamilton signs, and we bring Fleury back (both likely, as Hamilton is one of the guys we can't let go, and Fleury is just now coming into his own, and will probably not cost too much to re-up, and there is zero appetite from the front office to break in 2 rookie dmen in any given year) we will likely have 5 of our 6 defensive slots filled for at least 2 years. 2 of the 3 are going to be blocked. And even more curious, we took a guy from an area we need help in (RH depth forwards who can score) and made it weaker to create this logjam.
Something about this doesn't add up, unless there's a bigger move coming.
