You can't possibly make a good list after only 1 season of the new NHL. For all we know, maybe a couple of players played over their heads and maybe a couple had a tough season. I say let's wait for at least 3 complete seasons before making such list.
While I do think Chara is overpaid and overrated and the Sens made the right choice in choosing Redden over him....Markov>Chara
For me, its a tough call. It all depends what type of D you want, Markov is alot less likely to make mistakes in his own end. Chara can clear the front of the net with ease. Offensively I think Markov is the go to guy there
