if it was purely this year i would probably give rivera a small edge over kazmir, but in a dynasty league i think you have to keep the younger guy with the huge upside to the guy at the end of his career.

You have plenty of closers and potential closers, keeping Kazmir is the obvious choice. Mo-Riv is old as dirt. That's like trading James Loney for Lyle Overbay in a keeper league. It just doesn't make sense.
