I think more than that, people forget that in Sbisa's last year in Vancouver, he drastically improved. Not to say he was a great top 4 guy or anything, but he was much much less of a liability in his final year.
Not close right now, but that could be due to sample size. What we've seen so far this year rivals Lu and Schneids, but Luongo and Schneider could both consistently put up stellar numbers. We'll see if Marky and Demko can keep it up.
