By all time great Bruins, I meant that this is considering play while wearing a Bruins uniform. I think he fits comfortably in the top 10-15.
Top 15 out of what must be well over a thousand players would be top tier in my view.
I'd have a hard time putting him in my top 15 because I can think of 14 off the top of my head right now.
In no particular order..
Orr, Shore, Bourque, Esposito, Schmidt, Brimsek, Cowley, Chara, Bergeron, Clapper, Thompson, Bucyk, Neely, Middleton
I know there might be someone I forgot, but I think these guys are clearly better than Krejci.
Also, there are other issues as pointed out about how to weigh players who had better peaks but perhaps had a shorter time with the club. I will give weight to time served, but others will focus on peak. Also, players who played elsewhere for a long time like Oates, Park, Pederson, belong on the list and I am not sure where.
Current Bruins like Rask and Marchand could claim to be better and Pastrnak in the not too distant future.
