I think the above better represents a quality offensive player as compared to a 5x5.
It doesn't change a lot of values, but it makes players who just steal bases less valuable, and it makes players who just have average less valuable.

We have a max "starts" for a given matchup so it adds value to quality pitchers who go many innings, and keeps people from streaming.
