Unless it's already determined that he's a bust, give Kira the keys and let him drive the bus.
Memphis, arguably in a similar position as the Pelicans, cut ties with an above average point guard (the best player on their team, Mike Conley) and charged Ja with running the team from day one. In the long haul (and understand that's what we are looking at in New Orleans), Memphis will be better off for doing it early.
Now I realize that Kira may be no Ja by comparison, but the errors now being repeated over and over again by a four year professional would be better served if they were made by a 20 year old rookie while laying the foundation for tomorrows to come.
I guess what I'm saying is that shoddy play out four year veteran is unacceptable when compared to possible shoddy play of a 20 year old rookie (and that's the worst outcome). Maybe, the rookie might be a better pilot than # 2 is already, but only needs the chance to prove it.
