I'm looking at StubHub for a couple games and wondered which sections/rows recently were made more spacious. I had heard S Stadium nosebleed but that isn't very specific.
They announced that north stadium — rows 80 and above — and Section 14 in south stadium, rows 16-98, will have seats widened. I would consider the advice above about the 600 level, better view, better seats and better access to concessions.
