Very simple. You do realize that what you are asking about is position based. Besides that Jefferson is well known for having one of if not the best post games in the NBA. And lastly Jefferson is the more efficient offensive player. Last season Jefferson not only had the higher FG percentage but also the higher eFG% and the higher PER. Not only that but Jefferson also had the higher offensive rating and more offensive win shares. Clearly this is one that 2K got right.
You keep yelling about Melo getting a raise but when logic is posted to tell you why he doesn't deserve one you have no response.
