Value to a team is about helping your team win ballgames. Making outs or getting hits in a tough hitters park is the same at helping your team win as making outs or getting hits in a hitter friendly park.

Value is about production, and there always is a bit of luck involved in all production of runs. There's no need to account for luck when it comes to evaluating a players production or value to his team.
They absolutely tell us who the more productive player is. A run created in Colorado is not equal to a run created in Seattle.
