See the post made Mar. 1 about Uribe sustaining a stress fracture. If Hernandez has to play shortstop, he won't have the flexibility of a Boone (soon to be eligible at three infield positions). Hernandez will probably have more power, and his average will be OK, but Boone's average should not be as low as it was in 2002, and he showed that he could steal some bases - always valuable in fantasy. Your choice is tough, but if there are other decent shortstops available, you could take Boone and another shortstop, and play both of them.
