According to him right now (in no order) the Top 5 PG's are:
Wow, seems like Wall really likes Kyrie as a friend, he's always really "respectful" of him. As I think most people would agree right now that Kyrie Irving has yet to play like a top 5 PG...although he's def. one of the top 5 most popular PG's.
And I'm sure this list accounts for PG's who are not injured...even then the only PG who's injured right now that I think is better than Wall at present is Russ. Westbrook (D.Rose was terrible in his return, Rondo, w/o the HOF players, I'm doubtful).
He also states that Steph Curry is the hardest PG for him to guard (again of those who are healthy, I'm thinking Westbrook would be the toughest for him since he's basically a stronger version of himself with better teammates).
