Onstad, who turns 40 in January, and Waibel started for new Quakes coach Frank Yallop on the old Quakes' 2003 MLS Cup championship team. Cochrane played his college ball at Santa Clara University, where the Quakes will play their home games in 2008.
The draft will be held at 1 pm ET on Wednesday. San Jose may not claim more than one player from any given team in MLS, and three teams will not have a player taken in the expansion draft.
Trinidadian Avery John was only one starter for MLS Cup runner-up New England who was left unprotected.
Fifteen other players who started in the MLS playoffs were left unprotected.
FC Dallas has five, including Designated Player Denilson. The others up for grabs are Argentine goalie Dario Sala and defenders Chris Gbandi, Clarence Goodson and Alex Yi.
Other unprotected playoff starters are French Laurent Merlin, Ramon Nunez and Alex Zotinca (Chivas USA), Diego Gutierrez (Chicago), Brian Carroll, Guy Kpene and Greg Vanney (D.C. United), Kevin Hartman (Kansas City) and Francis Doe and Joseph Vide (New York).
Among the players who played for Yallop in 2007 at Los Angeles and whom the Galaxy left unprotected are veterans Peter Vagenas and Kyle Martino. (Clint Mathis, picked up a deal with New York Tuesday, was also made available.)
If recent history is any indication, the expansion draft won't be of much help to the Quakes.
From last year's expansion draft, one only out of 10 players taken by FC Toronto ever played for the Canadian club, and Brazilian Paulo Nagamura played all of four games before being traded to Chivas USA.
