He would certainly be expensive....two of the Sox top prospects and maybe something else....but if you were going to move top prospects...why not for another top prospect?
On a side note I've heard from a lot of scouts and people who observe the minors closely....that all say Hanley Ramirez is better than Aaron Hill and Robinson Cano
Aaron Hill - .341 AVG, .398 OBP, .478 SLG
Robinson Cano - .302 AVG, .324 OBP, .465 SLG
.....as long as he can show some games at 2B.....I expect he jumps up soon....I really want to see what this kid can do
