the other thing that would be nice to see is analysis around how many runs a year you are losing with a weaker armed SS that can hit, versus a guy like Florimon. It seems like it is a hard and fast "this guy does not have the arm for SS", but we are then OK with Florimon hitting .220. If you assume Polanco to be a: .280 hitter with a .740 OPS, 45 extra base hits a year, with 50-60 BB. Polanco and Florimon field at the same clip, but Polanco fails to throw out 15 guys that Florimon would throw out..... You would think you could model this out and make a strong case that on balance, Polanco would be a better SS. Over 600 at bats, you are getting 36 more hits, 20-25 more extra base hits, and you are on base another 45-50 times.
