Piazza's Telling Omission

It seems to be a conspicuous absence that Tom Boswell's column praising "clean" Ken Griffey, Jr's election to the Baseball Hall of Fame makes absolutely no mention of the other player elected along with Griffey, Mike Piazza.

Piazza has long been suspected but never been proven of taking PEDs. I guess we know what Boswell thinks of the rumors since he appears to have gone out of his way to exclude any mention of Piazza in the piece.
