How many closers does a team actually need?

my guess is your prolly winning or at least top 3 in the saves category??? so you dont want to be getting rid of anyone cuz you have atleast 10 points locked up cuz you have pretty decent closers who have amassed alot of saves already......you dont want to be trading 1 away and then slipping in the saves category because of it...you know closers are going to close you dont always no how the hitters are going to do ...so stand pat and goodluck the rest of the way
