Dano also had sheer longevity (23 years is an accomplishment in itself), and the fact he was an 'original Devil' on his side. Brylin parachuted in from '95 on but Dano was there during practically all of the dark early days. Nothing against Brylin but you left out those two very important factors.
Brylin played professionally for 20 years, just not all in North America. Daneyko being around since the beginning makes for one hell of a story but still does not put him in the same category as Stevens, Brodeur and Niedermayer.
Let's say in some alternate universe Brodeur, Niedermayer and Stevens all had their jerseys retired 1-2-3. With that precedent set, I don't think Daneyko's would go up fourth.
