please check out my post on whether to keep lester or kennedy. i'm not keeping michael young. would like to know your choice and why. viewtopic.php?t=436990
as for your keepers,
i'd definitely keep zobrist over bruce. zobrist's average line last 3 years:
.268, 19 hr, 89 runs, 86 rbis, 20 sbs. at second base. he is a no-brainer. bruce is only above average in 2 categories and he's an outfielder.
i'd keep kennedy over wilson. tiebreaker is the nl west.
