No they don't. He's not in the same stratosphere and their fans are well aware of it. He's a small offensively dynamic player who may top out as a middle pairing dman but is more likely a bottom pair + top PP dman. I'm 99% sure that virtually every poster whose mentioned Murphy in this thread has confused him with Faulk, who IS very comparable to McD and is valued as such.
Agreed, he also of course has a lot of potential as almost a 1-way offensive minded D, he is really slick with the puck, but he hasn't really stood out at the NHL level yet.
