aI would like to find one of the crystal balls so many here seem to be gazing through.
Julien has shown he has large gaps, in his performance; he is below average at Second on his best day., and some here think if he keeps batting agaist pitchers that already own him, he will magically get better, good grief.
Polance in 4 seasons at Second is average, not below.
Lee is an unknown rookie; could come up and not be below average in any manner, or could be another De La Cruz: come up and looking like the next Joe Mauer , and then quickly fall down to Celestino level.
IF, if they would trade both it would be foolish to do so for any pitcher not at leaat at Gray's level, but that will never happen.
