This is the most common misconception. In NBA 2K17, "Skill Points" (SP) were the offline currency. "Virtual Currency" (VC) was the online currency used for MyTEAM and the Park. Because this glitch requires the console to be disconnected from the internet, you never earn VC. You earn raw SP. You cannot take this player to the Pro-Am or Park. This is strictly a single-player, offline god-mode glitch.
NBA 2K17 is widely regarded as one of the most mechanically sound basketball simulations of the modern era. However, its MyCAREER mode had a notorious flaw: the grind was brutal. On last-gen consoles (PS3/Xbox 360) and early versions of current-gen before patches, earning Skill Points (SP) to upgrade your player from a 55 overall to a 99 overall required hundreds of hours of legitimate gameplay.
Users can search for their current SP value, spend a few points, then search for the new value to find the specific memory address and set it to a high number (e.g., 999,999).
