As the modern-day Boston Bruins get ready to host the up-to-the-moment Chicago Blackhawks tonight at TD Garden, let’s cast back, quickly, to a 1948 version of the rivalry at the old Boston Garden. The two Blackhawks in view aren’t so easily identifiable, but I’ll guess that’s Red Hamill up front and (maybe?) Bud Poile farther back. The Bruins are led by the helmeted Jack Crawford, with Clare Martin (19), Woody Dumart (14), and (way back) Wally Wilson (22) among his followers. Tonight’s meeting is the 591st between the teams, with Boston having made the better of the match-up since 1926 by a count of 268-230-79-4. The Bruins have outscored the Blackhawks, too, in toto, 1,859 to 1,785. At home, the Bruins are 168-92-34-0 all-time versus the Blackhawks, having scored 1,058 goals to Chicago’s 830 in those 294 games.
