The True Dollar Journal's NHL True Score™ ranking system relies upon actual performance upon the ice. It is a mathematically derived ranking and no subjectivity goes into the calculation other than observational assumptions that is the basis for the mathematical formula.
Of course, sport does not come down to mathematics and past performance in no way guarantees a future.
Tested during the 2017-2018 season, the ranking provides an excellent snapshot as to which teams will make the Stanley Cup playoffs.
