I'm back!
I suppose this depends on whether you believe that 2012 Ludwick (who is a slightly less effective imitation of 2008 Ludwick from StL) is the real one. I think Keri's point is that if you look at his career numbers, Ludwick is in for some sort of regression this year. If that happens, then the Reds are choosing between two rather mediocre OF with different skills.
