NBA 2K17 is not free, however there is a free mini-game called NBA2K17: The Prelude. This mini-game allows you to create your player to compete in the MyCareer mode.

You don't play an entire college career, but a few key games that will help determine your draft status. You don't even play full games, only two 6 minute halves.
