Lakers have a young roster. Jeanie Buss needs to look into hiring someone like her fiancé was at one time. Someone who is young and successful in the minor league system. Those guys turn into good coaches.
I'd want to talk with someone like David Blatt. Messina is another guy who did well overseas but he may just take Pop's place in 3 years. Luke Walton is real young but did more than enough to make sure the Warriors didn't miss a beat. How would he do with less talent?
I'd also want to talk with a few of the hungry young'uns who have been successful in the D-League -- like Jordi Fernandez, Casey Hill, Nate Bjorkgren, or Nevada Smith.
The Lakers don't need retreads. They need a fresh face.
