Fantasy question for the community:

Keeper league. I'd deal Nick Swisher and Chris Perez for Michael Taylor, Randy Wells, Marc Rzepczynski. It's a custom 7x7 scoring league that uses OBP and OPS rather than BA, so Swisher's value gets a big bump. Saves are severely devalued though as we use S+HD, so bullpen arms with a lot of holds can be picked up off waivers easily ... I would be dropping Perez to make room, so he is a throw in. Is this enough of a return for a high OBP bat like Swisher? Wells and Rzepcynski have both surprised, can they keep it up going forward? Thanks for your thoughts!
