While the new on-ice look for the Spoked-B will be the most glaringly obvious change for the B’s in 2023-24, it’ll only be one of many differences for these new-look Bruins, set to take the ice without either Bergeron or Krejci in the lineup for the first time in over two decades.Even with Marchand, the longest-tenured Bruin, still around as the guiding hand, the keys largely belong to the next wave.
