Can someone help with picking seats in Vegas' T-Mobile Arena?

I'm planning to see a hockey game at the new T-Mobile Arena on my trip to Vegas in December. I checked Ticketmaster's prices, and they're very strange to me.

I like seats near corners. I found tickets in Sec. 217 row D for $55 and row G for $48. In similar sections, a row D ticket goes for $105 and row G for $94. It's a brand new arena, so there shouldn't be obstructions.

Does anyone know why the costs of similar seats vary so much at T-Mobile?
