When you’re 38 wins over two seasons bad, you need a lot of things. You need better players (or, maybe just for the ones you have to realize their potential soon). You need better decision making from those who run the organization. And you need better coaching.
The Lakers have, hopefully, addressed that last part and are working on the players and decision making part. Free agency success, internal growth, and a front office who seems to have an idea of where they want to go post Kobe Bryant would all be nice.
Of those things mentioned, however, the only one actually in place as of now is the coach.
