Those are almost exactly the numbers I have from the MLBPA - and the %'s decreases I cited are correct. I'm confused by your post.
Year to year increases have declined from an approx. 15% annual rate (1998-1999) to about 3% this last year. They have declined for 4 years in a row now.
That is no coincidence IMO.
As for the foreign player impact - With the influx of quality foreign players - in addition to the steady supply of homegrown quality players - there is simply more to choose from. That is most likely why the "demand" competition has lessened.
Either way - it sure is lucrative for all who make it to that level.
