I really have no idea if the figures they use are correct and I’m honestly not sure where they came up with them or why yours are lower than theirs. Maybe higher numbers are appropriate. It seems to be you’d need a HUGE amount of information in terms of the availability of MLB quality players at those positions.
This is one of the several reasons I honestly preferred Win Shares.
Playing right field can be lonely and dull
Little Leagues never have lefties that pull
I dreamed of the day a hit went my way
They never did, but still I would pray
That I’d make a fantastic catch on the run
And not lose the ball in the sun
And then I’d awake from this long reverie
And pray that the ball never came out to me
