There are two distinct setups for seating behind the basket in the lower level. The first setup has sections 108-112 and 120-124 starting at row A and continuing through row Y - like most lower level sections. In the other setup, rows A-Q are removed and only rows R-Y are available.
In either setup, you'll probably want to aim for rows R-Y. Ticket prices are less expensive, the seats are closer to the concourse tunnel (fewer stairs to walk) and the seats are permanent - which tend to be more comfortable.
Furthermore, sections 110 and 122 are directly behind their respective baskets. Skip these in favor of seats more in the corner where the basket is not as obstructive.
