I have no issue with Subban being behind Chara, Weber, Doughty, Suter, Karlsson and Keith. Those are big time players.
Chara, Weber, and Doughty are all ahead of Subban, yes.
Karlsson? We've been here before. Karlsson is better offensively as Karlsson is ahead of every other blueliner offensively and in the past few years only Mike Green at his best has been anywhere near the same league as Karlsson offensively.
Suter and Keith are overrated, and Subban is better than both of them. Well, Keith is debatable, but his offense is inconsistent and the Keith-Seabrook partnership is more democratic than anyone Subban has played with.
When it comes to Suter, I can confidently say Subban is better. For all the praise he got for his minutes last year, he got slaughtered on possession. By the end of the year he wasn't even the best defender on his team considering how good Brodin looked.
