i disagree. i kept nba 2k11 with 2012 rosters (i didn't like 2012 at all). True that 2k13 is a bit too generous on the offensive side, but in transition, right stick ball handling, animations and physicality is way superior to nba2k11.
And then again you can always alter the game with sliders.
i'd say nba2k13 is probably the best sport game of the ps3/360 generation.
+1, and I would add that passing is much much better than 2k11 and speed is a factor, much better again than in 2k11. The only thing 2k11 has that 2k13 don't is the Jordan challenges.
But gameplay-wise, is the best sports game I've ever played, no question about it.
