Canucks fans who were sad to see Cody Hodgson leave on Monday at the trade deadline didn’t have long to wait for him to return to Vancouver. He’s back in town tonight, albeit with the Buffalo Sabres. Also back is Christian Ehrhoff, who left town in the offseason, signing a 10-year, $40 million deal with the Sabres. Both Hodgson and Ehrhoff make me think about how our perceptions of players are formed. In particular, they make me think of David Booth.
