Campbell has played every position except for C. He must look really rough at 3b as he only has 5 appearances there.
I'd rather Mayer up the middle, but Bregman built a career being a MIF playing and above average 3b. Is there less wear and tear over there? I don't think that much. I guess it's just the option they are stuck with at the moment.
I wouldn't sign Breggie for 5 years. We already saw what his body looked like in year one.
