For obvious reasons, be it history, or be it recent memory, the Habs are the Bruins’ rivals. No ifs, ands, or buts about it. Hate ‘em, hate their guts, hope nothin’ but the bad things in life happen to them and nobody else but them etc. etc.
And a Rivalry is always much more vicious when the home team just can’t seem to put their enemy down. Being bested in spite of themselves, or perhaps because it’s who they are.
Since before the turn of the decade, Boston has largely under-performed against the Canadiens, whether or not they were the better squad.
