Presentation, Commentary, pre-game and of course gameplay, all traits that make 2K5 so dam good.
Also unlike Madden, 2K5 always kept you on your toes, never felt repetitive or scripted *cough EA*
Honestly, the best thing EA could do to save the franchise would be removing Cash Ultimate Team, switching the frostbite engine out with something more sport friendly, and for Christ's sakes get rid of Charles and Brandon.
