Is there an NHL team that has never had a player of color on the roster?
going through every team with the first name off the top of my head:
anaheim - ray emery
arizona - anthony duclair
boston - willie o'ree
buffalo - mike grier
calgary - jarome iginla
carolina - ray neufeld
chicago - dustin byfuglien
colorado - chris stewart
columbus - raffi torres/manny malhotra
dallas - trevor daley
detroit - andreas athanasiou
edmonton - grant fuhr
florida - peter worrell
las vegas - malcolm subban (who only came to mind because c1958 mentioned him above)
los angeles - wayne simmonds
minnesota - richard park
montreal - pk subban
nashville - joel ward
new jersey - claude vilgrain
new york islanders - kevin weekes
new york rangers - anson carter
ottawa - ray emery
philadelphia - wayne simmonds
pittsburgh - jim paek
san jose - joel ward
st louis - chris stewart
tampa bay - kevin weekes
toronto - off the top of my head i can't think of one other than val james but i'm sure there are a bunch
vancouver - anson carter
washington - joel ward
winnipeg - evander kane
so no, there are no teams with exclusively caucasian/caucasian-presenting histories.
