11. Oscar Robertson
Game: NBA 2K13
Just because he doesn't look like an All-Pro linebacker doesn't mean the man they called the Big "O" isn't every bit the multi-dimensional player that King James is.
Go ahead: dial up the 1970-71 Milwaukee Bucks (who are sadly lacking Lew Alcindor, an addition which would make this squad one of the best in NBA 2K history) and see what happens. Without even trying to, Robertson is likely to end up with 15 points, 7 assists and 6 rebounds. Or better yet, put him on a different team with some serious low-post options and wing help and watch him go for 25, 10 and 10. At 6'5", Robertson is a big guard, plus he has a smooth and easy-to-use shooting stroke that makes him great off the dribble or spotting up.
For the next fantasy Association you run, I highly recommend ditching one of the weaker NBA teams and adding in Robertson's Bucks in order to build around him. You won't be sorry.
