I like this a lot.  It reminds me of the graphics Flip Flop Fly Ball has on their website.  It would be nice to have a link to a higher resolution since the smaller names are impossible to read and in some cases difficult to discern colour, but that doesn’t really change the effect or meaning any.

I think the font size alone works pretty well for me without adjusting for length.  Comparing Jeter and Sabathia, for example, the difference in font size jumps out at me much more readily than how their salaries compare.  Rodriguez does dominate the graphic, but his font size is legitimately huge compared to everyone else’s.  At least for me, the font size works pretty intuitively.  Nice work.

I agree with post #1, you should at least make the kerning of the letters relative to the players’ name, so Rodriguez has less space between the letters than Jeter to accommodate for the name difference.

I think your Wang is *way* outta place. 

That’s not where my anatomy textbook shows it, at all.
