Arcia is often compared to a pre-knee injury Jason Kubel.
For those that dont remember, pre injury Kubel was considered a well above average OF with a solid arm & some speed (16sb in 04). After surgery, he had no range/speed left. IF that's the case defensively, Id take it. Never heard on any reports that he cant play the field just that with weight gain, he's no longer able to play CF. He is considered to have a strong arm, even after the surgery.
When he gets called up in Sept, we can see for ourselves, I hope.
