Fantasy baseball all-stars that I've dropped from one of my teams, which is in a 10 team league (I've also included their current Yahoo! player-rater ranking in parenthesis):

Adrian Beltre (5)
Dropped for Kelvim Escobar (145) on June 8th. I already had Mark Teixeira and Hank Blalock on my roster, so I dumped the current ML HR leader because he had some injury issues.

Jason Schmidt (9)
Traded for Josh Beckett (228) on April 5th. I was worried about Schmidt's offseason shoulder surgery. I should've been more worried about Beckett's blisters.

Ben Sheets (28)
Dropped for Adam Eaton (153) on April 8th. Sheets' first start of the year was his shortest. Had I waited 2 more days, there's no way I would've dropped him after a 6 IP, 0 R, 0 BB, 10 K performance.

Jeromy Burnitz (32)
Dropped for LaTroy Hawkins (128) on May 16th.

Carlos Lee (37)
Dropped for Wilson Alvarez (159) on May 12th.

Livan Hernandez (82)
Dropped for David Riske (254) on March 20th. I wanted a closer-- too bad I didn't get one.

Despite all these bad moves, I'm in 2nd place in this league. I ended up making trades to get Carlos Lee and Livan Hernandez back onto my roster, but I just wonder how I'd be doing with Beltre, Schmidt, Sheets, and Burnitz as well.
