Catcher Buster Posey seriously injured during collision, should the Giants have him change posistions?

No, they should keep him at catcher. The Giants should not move Posey to another position based on one injury. The reason why Posey is a special player is because he can provide offense at catcher. Posey's offense would allow him to play other positions, and he would be an all-star at first, third, or the outfield due to his athleticism. Still, it's his value at catcher that sets him apart. Apart from Joe Mauer, there aren't many catchers who can hit like Posey. Don't forget his leadership abilities, and the way that he works with the Giants pitching staff. Buster Posey is a young guy, but is getting a lot of respect for the way he leads from his catching position. It's no coincidence that the Giants won the World Series last year with him behind the plate.
