Actually I am also a member in this league. We are holding a form of rule 5 draft where we can protect 40 players from our MLB and minor rosters.
As an example i released Huber, Matt Bush, Head and Meyer.
I protected the following minors (* must be added to MLB roster in 2007): Butler, Billingsley*, Bianchi,Callaspo, Duncan, Escobar, Gorzelanny*, Herrera, Hurley, Adam Jones, Loney, R. Martin*, Milledge, Adam Miller, Nippert*, Patton, Pennington, Span, Swarzack, Sweeney, Tabata, Tulowitzki, Wainwright*, Weaver*, Delwyn Young. So the only player I released that I had 2nd thoughts on was Huber and I felt his 2007 role in KC was likely to be limited.
