Baseball Musings published an early version of the Marels projection (MusingsMarcel). They did only position players right now, but it's always fun to look at projections. The Marcels are usually done by Tangotiger and he'll probably do them for 2014. These are based on Tango's Marcels method. Below are the Cubs players currently on their 40-man roster. Only players who played last season were included and Marcels assumes any player who hasn't yet played will be average. Obviously this is not accurate, but the Marcels projections are the simplest of the bunch. They are also about as accurate as any of the others.
Yeah, so basically the Cubs offense will suck unless they go outside the system to add players.
