Ranking Goalies: A Lesson in Clarity

[Leafs2010]

Justin, I asked this in the other thread but you may have overlooked it so I'll ask again here.

Regarding Kipper, any insight as to why he posted a weak GAA/SV% in 2007 and 2008. What changed last year that enabled him to put up elite numbers?

How close is it between Rinne and Halak? Most people seem to rank Rinne higher, but your rankings have Halak ahead by 1 spot. Halak's GAA and SV% were quite a bit better than Rinne last year, while their shutout ratio was similar. Do you see both goalies playing 70 games and approaching 40W this year?
Another concern for Rinne is you mention his streakiness... Combined with the Preds tendency to have a tight leash on their starters, it adds a bit of risk too, doesn't it?
