As a Ranger, fine. Doesn't look right, but I can live with that. But as a Bruins, that's sacriligeous after all the wars and the crap between the two.
Guy Lafleur as a Nordique. He was the first name in a dynasty and after the wars between those two teams.
Any other player that was an important part of a dynasty like mentioned above, guys like Savard, Lapointe, Robinson, Shutt in other uniforms. Clark Gillies comes to mind.
Bernie Federko is another that comes to mind.
Nilan actually got an ovation at the old Boston Garden when he was first introduced as a Bruin in October of 1990. He played high school(Catholic Memorial) and college(Northeastern) in Boston and grew up idolizing the Bruins in the 70's.
