I'm in a keeper league with four keepers. Not sure whats the best way to go about picking players to keep. This is my roster.

Sidney Crosby C PIT

Denny Briere C PHI

Patrice Bergeron C BOS

Henrik Zetterberg C DET

Matt Duchene C COL

Ryane Clowe LW SAN

Ryan Malone LW TB

Bryan Little RW ALT

Milan Hejduk RW COL

Kris Letang D PIT

Keith Yandle D PHO

Shea Weber D NAS

Alexander Edler D VAN

Jonas Hiler G ANA

Jimmy Howard G DET

Corey Crawford G CHI

I have a long time to figure it out but not sure if age, rank, position or some of all of these things are the best way to pick my keepers. If I had to pick right now I would pick Sidney Crosby, Matt Duchene, Kris Letang and Jonas Hiler. Can anyone tell me if these are good picks? If not what are better picks and why? Thanks for the help
