Kronwall actually had less give-aways than Shea Weber, Myers, Chara, Hamonic, Byflugien, Klingberg, Subban, Burns, Karlsson, Wideman, Brodie, Karlsson, Yandle, Doughty, Markov, Trouba, Niskanen, Hjalmarsson, Lindholm, Hedman, Seabrook, Keith, Green, Mcdonagh, Girardi, Letang... and many more.
The only number 1 D-men who turned the puck over less than him were OEL, Piertangelo, Giordano, Shattenkirk, Wisniewski, and Phaneuf.
And those are totals, not counting injuries/time missed that guys like Giordano sustained.
You're right. 52 for Kronwall, 58 for Ericsson (Shocker). I think most offensive defensemen lead in giveaways but what disappoints me the most is that Kronwall was suppose to develop this two-way game and sadly I feel he hasn't reached his full-potential of his two-way game.
