That's nice quick look at some large sample stats in correlation to success.
Shots usually among the best for Cup winners.
Same with goal differential, which has been known for decades.
On top of that, shooting percentage doesn't seem to matter much. It's up and down from year to year.
To me a takeaway from those three stats, is that throwing pucks on net is a good strategy. Another thing that backs up what many coaches have been preaching for a long time.
Payroll seems to be just as important as it's always been.
Goal scoring and having one of the best offensive teams seems to go hand and hand with Cup winners.
Wish they had a goals against table.
PP/PK success was interesting. Obviously you can win without having a good percentage on either one, but it seems the Cup winners were among the best in the league in PK more often than the PP.
Depends a lot on your strengths and weaknesses in other areas, but those are some good numbers for the age old debate of which is more important. PP or PK.
To further prove that one stat isn't everything though, 7 out of the 16 years the team that lost in the finals had a better PK than the Cup winner. Same with the team that lost in the finals 7 times being a better offensive team than the Cup winner.
