I think there are only three on their radar - Powers-Johnson, Frazier and Barton.
At this point I'm in agreement that the Steelers are most likely to address right tackle in the first round. If they do not, however, then there's a very good chance Powers-Johnson out of Oregon is the reason.
Many believe his best NFL position is center, even if he doesn't have an extensive history playing there.
Barton is another player they likely need to draft earlier than their native second-round pick at 51.
