Niemi is a really solid pick for this season.
He's playing his 3rd or 4th year in San Jose and has a consistent group of D-men in front of him: Boyle, Burns, Vlasic, D.Murray. Now they've also added Brad Stuart, so their D-men are very solid.
In a full season, I'd peg him for 35 wins.
I think he was the best "value" goalie to draft in Yahoo! leagues this year (based on where they pegged him). Of course, in a league with smart owners, it really didn't matter because Niemi was going in the top 20 goalies, regardless of Yahoo!s misguided rank of him.
