Let's be careful with these give away stats...take a look at the top 10 on these stats, you'd take EVERY player on this list (Chara, Seabrook, Daughty, Jamie Benn). You need the puck on your stick all the time to make this list...yes, there are give-aways but there is also offence generated.
I wouldn't take Chara. Too old and too expensive.
But like i said earlier, the problem with Subban isn't what he does on the ice. Sure, even if his team sucks offensively in all aspects which makes you wonder what exactly does he bring to the team.
His problem is his presence. Too much of a distraction around the team. More than half the players on the team hate his guts. He acts like he's way bigger than the team and the coach has lost control over him. He also doesn't respect Max Pacioretty as a captain. He feels he should be the captain or someone else other than Pacioretty.
As i also mentioned, only a coach (like Babcock, among a few others) that Subban respects will make him play better and be less of a distraction around the team.
And as i mentioned also, his value will never be higher than it is now. The time to trade is now and the habs should definitely trade him before Subban gains total control of his destiny and will be holding all the cards. Would i want him on the Leafs? Not for $9 million per year. That number's a cap-killer!
