Yes this is called "the source" but it doesn't answer the question of how minimum games played factor into these numbers. 14 goalies in front of Howard have played 3 games or less, which pretty much puts your statistics on Howard in the null and void column. He is currently in company with these awful goaltenders going by what you are looking at on NHL.com; Miller, Lundqvist, Ward, Backstrom, and Fleury. Statistically he's ahead of Quick, Bryzgalov, Smith, and Halak respectively.
So unless you are considering Yann Danis the best goalie in the league this year, who sits at number 1 on your list along with Chad Johnson and Darcy Krumper who also are on top of the list from your source, the numbers you offer are just flat out wrong. You can't really count one or two games played by backup goalies and throw Howard that far down the rankings, not quite how stats work in this argument.
