NBA 2K15

From the MyCAREER menu, go to Player Upgrades and Attribute Upgrades. Instead of buying increases for individual attributes like previous years, you will have 6 areas that you can spend VC (Virtual Currency) on that upgrade several attributes at once. This achievement will pop once you've fully upgraded one of the 6 categories of attribute increases.

The cheapest category will be the one that helps your position the least. For example, on my Point Guard, it is only 21,487 VC to fully upgrade the Rebounder category from nothing to full, while Inside Scorer would cost 37,401 VC. Another example is Power Forward, which costs only 13,890 to fully upgrade Playmaker, but 60,900 to fully upgrade Inside Scorer. You could just go the cheapest route just for this achievement, but I would recommend upgrading the category that will help you most at your position as you play through MyCAREER, since you need to do well in order to get the rest of the MyCAREER achievements.

Ways to get VC to spend on this achievement and others:
-Spend real money. This is obviously not the most desired method.
-Play games. You'll get more VC depending on your performance.
-Locker Codes which are tweeted out occasionally by @Ronnie2K and will also show up in news articles from time to time.
-Get the MyNBA2K15 app for your phone or tablet and you can get the following every day:
-500 VC for playing 10 Quick Games in MyTeam Mobile every 24 hours.
-300-3000 VC for drawing cards in the Daily VC Bonus game every 24 hours. Try to match 3 of the same card for double VC.
-50 VC for each correctly picked real-life game winner each day in Pick and Win. Get your picks in before the games start, usually by 7pm ET unless there are day games.
