Doesn't really matter. He was drafted to be our swing tackle and he'll be delighted to play either OT when we get injuries there. Until then, he'd rather play OG than sit the bench. The only reason we're listing him as an OG right now is because we're trying (hopelessly) not to tip our hand about drafting 2 OG's. Realistically, every team in the NFL knows we NEED 2 new starting OG's and Bushrod isn't one of them.
Honestly, I'm not a "fan" of Bushrod, but when Albert gets injured (happens EVERY year), I feel better with Bushrod manning our LT position and James staying at RT than I am with Fox in the lineup or forcing a massive position change domino effect with James out of position at LT, new rookie OG out of position at RT, and some other OL plugged in at OG. So, I'm OK with this.
