Are we taking into account what happened as their primes started to dwindle down? Because while technically Chara is past normal prime years for players, he's still playing at an elite level and considered to be in the top three for his position. Lindros post prime was a shell due to the concussions and injuries.
Lindros for just the prime years alone.
Chara for the longevity and being elite for nearly a decade now.
Then you also have to take into account their leadership abilities. Both were captains, but Chara has been lauded for his leadership skills in Boston. Lindros was not. I think the answer is a lot closer than people think once you start looking at what it really means to build a franchise and who you want to be leading it. When you're looking to build a franchise around a player, you should not only look at their skills as a player but their ability to be a leader of men.
As long as you want to consider that Chara didn't reach his prime until much later.
I'm not high, but I don't know what day it is.
