Corner seating in the 200 level is a great way to enjoy a Cavs game on a budget. These seats are vastly under-rated and are a great alternative to more expensive upper level seating near mid-court.
Sections 206, 211, 223 and 228 are adjacent to the higher-priced sideline sections but offer a similar experience. These sections have very good sightlines and the baskets barely get in the way of the view. Other corner sections also offer impressive sightlines but are slightly more distracted by being behind the basket.
Consider tickets in the lowest rows first - even if the pricetag is slightly higher. The views are vastly superior to the higher rows and you'll be closer to the concourse tunnel located at row 3. Another advantage of lower rows (especially in 3-8) is that they contain fewer seats than rows 9 and above - allowing you to more easily get in and out if you're stuck in the middle of the row.
