Another thing, Wan Weiqiang is not a proper PF. Don't worry about his outside skills. You need a proper PF. Getting a proper PF will help way more than Wan Weiqiang. It will help because you will improve your reb, and scoring + overall def. This games engine works mainly on attack v def. A PF with good outside scoring will not do much for your team playing outside when he can not score inside or defend inside. Aim for proficient inside if you can afford it, plus, mediocre skills everywhere else especially handling as a minimum.
