If you're looking toward next year, projections are starting to become available.
Dan Syzmborski's ZiPS projections for the Cubs are available, and I must say I really dig the presentation.
Rally hasn't gotten his CHONE projections for hitters and pitchers out yet, but his defensive projections are available.
SG's CAIRO projections are out, which include defensive projections based upon STATS ZR as well.
Tom Tango hasn't published his Marcels yet, but I've published my reimplementation of the Marcels.
