Not to mention the things we know about the Rangers even aside from on ice product:
Treat their players amazing
Yea, they certainly treated "Captain Cally" well. Many of the teams he's got on his list treat their players well.
Greatest city in the world
Subjective.
Overrated as a building. But it does have its drawing power legacy wise to some.
Original 6
Big deal. So are Boston, Chicago and Toronto. The Original 6 hasn't been a thing in 50 years. There is no player in the league who was alive when the Original 6 was a thing and there hasn't been in decades. A 23 year old is unlikely to give a crap about "Original 6".
One of the largest fan bases in the league
Fair point. Literally the only one you've offered. Almost every game is like a home game unless its against one of the other teams with a huge footprint.
Most valuable franchise in the league
The salary cap makes this completely irrelevant. Pre-salary cap, its huge.
