I feel the same way. Maybe I don't play the game as much as others but nothing about the screenshots, except for the new jerseys and maybe the shoes, stand out as being a improvement from last year. If the article didn't say 2k16 screenshot I probably would have assumed it was 2k15, again except for the jerseys.
Imo the other game is looking better graphically for what it's worth. Still the big factors will be how do the games look in motion and, more importantly, how do they play. If 2k has the superior gameplay I won't mind if the graphics are inferior.
