Roberts Likely Did Not Recommend Miers

From yesterday's WaPost:

It was John G. Roberts Jr., now the chief justice of the United States, who suggested Miers to Bush as a possible Supreme Court justice, according to the book. Miers, the White House counsel and a Bush loyalist from Texas, did not want the job, but Bush and first lady Laura Bush prevailed on her to accept the nomination, Draper writes.

... Roberts rejected Draper's report when asked about it last night.

"The account is not true," said Supreme Court spokeswoman Kathy Arberg, after consulting with Roberts. "The chief justice did not suggest Harriet Miers to the president."

This strikes me as a bogus accusation.  Why would one of the most experienced Supreme Court Justices recommend one of the least exerienced nominees?
