Evidently "very well-written" grant proposals don't get funded because it's just inconceivable that a student could sythesize such an "outstanding document" without their mentor having a "very hands-on role in putting this reasearch application together":
"The research plan itself is by far the strength of this application. It is very well-written and 'tight,' it is an interesting and important topic, and there are simply no major flaws. The quality of the application, and in particular the writing style, is somewhat difficult to reconcile. . . It seems evident that the sponsor played a very hands-on role in putting this research application together."
I can't win.
