Lakers need to start over and not skip the "building" process of a real team. Having a generational player or a core of elite guys gives you this luxury but when you don't have an generational guy you need to draft, develop, keep the pieces you want and trade the guys that don't fit until you create a core worth plug pieces in with.
It's a myth that Lakers don't care about building the "traditional" way. Divac, Eddie Jones, Van Exel were all drafted by LA within 5 years and all played some role in getting to the Shaq and Kobe era. Shaq being traded was a direct factor in getting Bynum and LO. It's all a process. Giving away picks and overpaying guys like Nash was an attempt to skip this process of building and development and it has backfired like no other.
