Very much like it. I haven't done much but basically you create your player and your basic skills, then you get put into some reserve team with some other players and have to do well.
At the start you have "drills" that you can perform to try and improve your player, different training like shots, defending, stealing.
Then you play 6 games and try to impress enough to win a trial with an NBA team. During the games you get rated on well (or poorly) you play. It's like PES's BAL as well where you don't always start games and may start on the bench, then get taken off during breaks and brought back on later in the game.
Pretty much BAP:S but the training fleshes it out more.
Check out my post here, got a link to an article someone wrote, plus a video.
