When they start in NHL, they was not so different... maybe because he had a great mentor behind him with Lemieux in Pittsburgh... since the 1st game sid hit the NHL, crosby raise his defensive game year after year... mcdavid 9 years later, im not sure if i can say he had a signifiant upgrade in his defensive game... the 1st one was working hard in his biggest weakness because he want to be the best player possible to win cup and the second didn't. that part can be considerable like intangible.
See letang get a dangerous hit and saw crosby running into a fight to protect his guy with everybody seeing this, how do you think rest of the team feeling when your seeing your leader reacting that way? The rest of the team have no choice to follow you ... thats intangible ! you will never see mcdavid doing this, you will never see matthews doing this...
What was the diffenrece between the tampa bay lightningt who was swept by columbus and the team who won the cup a year later... they was not a better team and probably worst on paper... the answer is Intangible. They gave away jt miller who was a better player than probably everything they bring in this team. But they signed maroon, traded for goodrow and coleman and those player help to create a kind of brotherhood with everybody ready to sacrifice himself for his teammate... thats changed EVERYTHING for Tampa, that changed their mentality. If Intangible doesn't exist, tampa would not won the cup in 2020 but in 2019
Intangible are everything that can impact the game and you cant calculate
