And the other side of the add/drop coin, a partial list of guys I've dumped (pre-seaon rank versus current rank in parenthesis)
OF Jones (78 / 781)
2B, 3B Beckham (134 / 1019)
SP Peavy (136 / 944)
RP Gonzalez (259 / 870)
SP Lackey (126 / 971)
RP Hoffman (248 / 1041)
For reference, Jose Lopez is 144/841. He's also 865 for the month. But he's 40 in the last week!
One last thing - I dropped SP Liriano (140/144) a while back after a few poor outings, and was still able to get him back when he starting pitching better again. Yet another reason active leagues with more teams are better - if I drop someone like that, someone else should pick him up on the chance he gets better.
