Does the total win record take into consideration OT and shootout wins that only recently counted as an extra point??
It's like the Davos kid coming close to Pistol Pete's record when Pete didn't have a three point rule and didn't play five years
It doesn't, from what I can tell. Montreal in 1976/77 was 60 wins, 8 losses, 12 ties (80 total games, no overtime wins). Detroit in 1995/96 was 62 wins, 13 losses, and 7 ties (82 total games, no overtime wins). Tampa in 2028/19 was 62 wins, 20 losses, and no ties (82 games with 13 overtime wins, 4 OTL).
All three of these are different, hard to compare exactly. But you have to assume that Montreal would have won at least half of the 12 ties so they could have had at least 66 wins if not more. DET might have ended up with 65 or 66 wins also.
Right now, the Bruins are 58 wins, 17 losses (including 5 OTL). Boston is 8-5 in overtime games. So if you adjust their record to assume ties, they would be 50 wins, 12 losses, 13 ties, with 7 games remaining. Boston may end up with say 63 wins which you could compare to Tampa's 62 win season but Montreal and Detroit still have better seasons if you adjust for ties. Tampa would only have 49 wins by the old rules and Boston only say 55 wins (if they go 5-2).
Detroit won 62 of 82 and Montreal won 60 of 80. Detroit had 2 more games. Montreal had only 8 losses, Detroit had 12 losses. It is really hard to compare but I would say these are tied for the best two seasons ever. Boston may get to 63 wins total and beat Tampa but if adjusted for ties, that is only 55 wins, about top 10 at best all time if all seasons are normalized to exclude overtime wins.
This team really isn't even the best Bruins team ever (in terms of regular season record). The 1970/71 Bruins had 57 wins in only 78 games (along with 7 ties). This year's Bruins will have about 55 true wins (if overtime wins are excluded) in 82 games, if they finish 5-2.
Maybe this table will help (assuming Bruins go 5-2 in last 7 games):
Team Season Games True Wins OT Wins
Montreal 1976/77 80 60 0
Detroit 1995/96 82 62 0
Boston 1970/71 78 57 0
Tampa 2028/19 82 49 13
Boston 2022/23 82 55 8
Note, there are some other teams/seasons in this, I did not list them all. As I said, this year's Bruins would be about 10th best all time if everything was normalized.
