There are a total of 19 seats in Section 129 Row 22, with Seat 1 located on the aisle at the right side of the row (as you face the field), and Seat 19 on the aisle at the left.
The infamous Black Hole is located on the south side of the Coliseum, between sections 102 and 109. Unlike much of the seating on the sidelines, these sections are right on top of the field, creating an intimidating presence for visiting players and visiting fans.
If you prefer a less rambunctious setting, but still want to be close to the field, the front rows of Sections 127-130 have what you're looking for. These are just about at field level, which gives you almost the same perspective as a safety or a linebacker when a play comes in your direction.
With how low these seats are to the ground, it's not uncommon for fans to stand for a large number of plays. Consider seats in the last few rows of these sections to be less affected by the standing, to be close to the concourse and to be covered and possibly shaded by the 200 level ocverhang.
On the lowest level of the Oakland Coliseum behind both endzones is the Lower Reserved Endzone seating location. These seats can easily see the action when it is on the near side of the field, but it can be difficult when on the opposite end because it is far away and the field goal post is an occasional obstruction. Even though it can be an obstruction, the uprights in the view allows for sections 106 and 128 to have perfect views to determine if a field goal is made or missed. Most of these sections have a similar shape, leading to all of the sections in this seating location having 38 numbered rows.
