Yes, that's what I'm thinking. Somebody mentioned on here it was too expensive to remove the posts, so that I can understand. But there aren't that many seats behind them, so why even bother putting them in?
Not a big deal I guess, unless they sell those tickets to unsuspecting fans. I can't imagine they will be used often, but I'm sure they will be.
Edit: It appears they are not selling any tickets in those sections for any game (sections 201 and 208). Or sections 113 and 117, though those could be season ticket holders.
