MLE stands for "minor league equivalency" and the article is about forecasting performance statistics for rookie baseball players based on their minor league statistics.
I'm a member of the Statistical Analysis Committee of the Society for American Baseball Research. Neal Traven, committee chair, looked it over and provided comments before it was published.
It's about 5 column inches, plus an accompanying chart!
