As mentioned with seats in the lower level, corner sections are pushed far away from the court, due to the hockey-friendly shape of the arena. As such, when considering seats in a corner section, aim for one of the sections closest to the sideline. If you miss there, row placement becomes the key.
Sections 301, 305, 318 and 322 are adjacent to sideline sections and will have much better views than other corner sections because the basket is not as obstructive. If ticket prices in those sections are too expensive, aim for Row C in any other corner section. By sitting in a lower row, you won't be in the far reaches of the arena where seeing the court is difficult and where walking up and down the stairs is a burden.
