Re: Projecting Janish
In 1200 defensive innings (roughly a full season or the equivalent of 600 PAs worth of playing time), UZR rates Janish as a +10 glove while Dewan's thinks he's a +8 defender. Considering what Janish's potential value might be over a full season, for the purposes of calculating WAR, he starts out with 7.5 runs for playing shortstop and +20 runs for the difference between average (baseline) and replacement level over 600 PAs. So accepting the rough estimate of his defensive value, he'd be a 3.75 WAR (7.5+10+20) player before considering his bat. That means in order for him to be a 2 WAR player over a full season, he'd have to be no worse than a -17.5 run bat (wOBA=.295; something like .240/.320/.350).
It's possible that Janish could be a 1.5 to 2 WAR player over the course of a full season provided he could play a full season.
