Isn't Person a little on the Small side to play OLT? Do you think he is a better fit at Center? Could he be better than Barnes in time?
Maybe getting Person some time at Center is in reaction to Barrett Jones being injured and not looking that good in camp overall?
Person has looked pretty good at Tackle actually, and is the most likely candidate to be on the 53 man roster at this point. After Barnes and Joseph, I would expect Person to be that next guy.
Barnes is a non issue right now, and Rhaney doesn't look ready.
I know it is a natural reaction when this sort of stuff is posted. But I hesitate to read much more into it, other than adding some depth. I think all too often, people jump to conclusions, and read way more into these kind of moves, when there are so many variables that have to all happen for it ever come to fruition.
