I personally agree. Westbrook needs to be a 6th man but the Lakers have to sign a PG who can at least fake start for them. Maybe the buyout market? The issue is, Westbrook is the only one capable of fake starting.
There biggest issue is they have the toughest schedule in the NBA for the 2nd half of the season. It won't be easy and Sacramento and New Orleans are on their neck.
Bron is basically the 1st unit PG. It would probably be easier to find another 3-and-D guy on the buyout market as a starter.
