Definitely a good target. as could be Schneider, if they decide they want to keep Lundkvist instead.
Schneider may not be a well of offensive output, but he could potentially play on a first pairing as a big, mobile and physical D that can shield a smaller, more offensive pairing partner like, say, Harris (5'11").
Lundkvist would be, on the other hand, the more offensive D that could settle in alongside a more shutdown D like Guhle, or a physical D with the mobility to support him on the attack like Romanov.
There will also be a few talented RHDs likely available near the end of the 1st round and Montreal, if it doesn't land another 1st round pick at the trade deadline, could potentially move up from a very early 2nd round pick at the draft to land one such RHD.
However, the 21 year-old Lundkvist, or the 20-year old Schneider who is, for his part, already playing in the NHL are close best to landing in Montreal's lineup from the get-go.
