I hesitate to say it like this because I know it will read poorly relative to my intentions...but Chara wasn't that good...now, the italicized "that" is a matter of relativity both to the best all-time defensemen and to the league he was in...
What I mean is that he wasn't that talented from a technical perspective...not a great skater, not very good hands, not a noteworthy passer (again, relative to the greats), not a strong puck carrier unless he had a real head of steam going, and even then, he struggled to routinely make forecheckers miss...I mean, look at that top-60 list that was made a few years ago...does he have the worst puck skills on that list? Langway? Quackenbush?
Of course, Chara is terrific defensively...but he has a pretty unique set of limitations relative to the field and played in a pretty weak time for defensemen...it will be interesting to see how history remembers him...he's, what, a 6, 7, 8-time all-star or something right? That's a lotta dimp...no?
Where I do award major points is his ability to cross distinct eras...he was horrific early in his career, sure...but when he started coming on in Ottawa, he got some love, then the big sleep happened and the game changed and Chara came up on the other side absolute roses in a game that shouldn't have favored him...his PIMs went down on the other side of the lockout...that's very interesting to me.
