Bored as hell and I'm sure its been done before, but since nothing new, who would pick-I know its apples and oranges because of different eras, none the less who would pick. Keep in mind I picked guys on what they did as 49ers and not their previous teams if they came in via FA.
Charles Haley, Fred Dean, Michael Carter, Bryant Young-backed up by Cedrick Hardman
Patrick Willis, Keena Turner, Dave Wilcox-backed up Bill Romanowski
Eric Wright, Jimmy Johnson, Ronnie Lott, Merton Hanks-Backed by Dieon Sanders.
Note: I choose Jimmy because he was a better all around corner than Dione who was strictly a cover guy and good teams like the niners found ways to neutralize him. Merton-well I like the chicken dance
