Need help on who to drop and which of these 2 players to pick up :)?

iev got ryan doumit,mark texiera,jose lopez,g.atkins,hanley, j.loney,josh hamilton,ryan church, eric byrnes, david murphy,ryan zimmerman, christian guzman,victor martinez, luke scott,posada,and reed johnson. frankly im loaded on offense but i need depth at 2nd base, 2 of the more premier names that recently became available in my league are Olrando Hudson, Clint Barmes, and Erick Ayabar. i like barmes but he doesnt hit everyday hes in a platoon, ayabar bats 9th, and hudson isnt hdttign too well this year. i need depth at 2nd base so which of those 3 should i pick up and who should i drop? my pitching staff isnt important, but theyre amazing just for the record. i ened an answer fast before someone else in my league swoops one of them up. best answer within first 30mins gets the points
