You can restrict the report to individual teams, to players who've played in a minimum number of games and by position.

For the moment, traded players have their contributions broken down by the teams they've played for.  For example, Guillaume Latendresse has +3 GVT for Minnesota and -1.3 GVT for Montreal.  You won't see him listed at +1.7 anywhere.  I'll figure something out to combine multiple contributions like this.

Because GVT deals with goals above replacement, you can convert GVT to wins approximately by dividing by 6.  The exact number changes every year.

I'll post GVT for other years when I get a chance.
