Some key points you are wrong about. EA bought the rights to keep NCAA football exclusive as well, so 2k couldn't have made a college football game if they had wanted to.
The NCAA decided that it wanted too much money up front for the college basketball titles. While there was never an exclusive agreement signed for NCAA basketball by either party, the cost was so high that it would not justify any game company wasting resources due to the low sales volume that both the EA and 2Ks had.
The NCAA killed any future basketball titles itself, well before the court case had anything to do with college athletics.
