Mitchell Report Unused Evidence

It has not been widely reported at all but one piece of evidence obtained but not quoted or used in the Mitchell report was an old MLB yearbook of José Canseco's. Here are some of the messages written in it's pages and cover:

"Stay cool and don't do drugs! -ARod"
"It'll be a long winter but I'll see you at Robert Downey's parties! -Lennie D"
"For me it doesn't really matter what you stick in your @$$! -Mikey P"

That's just a few and the rest are just a damning but were deemed too circumstantial. Go figure...
