Can OG play guard & Fisher play TE?

[*psychdoctor*]

I know Forum members loathe the idea of moving players to different positions but I'm asking serious questions here...

Can they move Og to offensive guard? Does he have the the leg strength and footwork to be better at guard than he is at left tackle?

I know Fisher has had some experience playing tight end in college and even occasionally as a pro. But since Fisher is underwhelming at right tackle he can lose weight and play tight end?

I just have no confidence in either at their current positions.
