If I was thinking about signing a vet leader for mentoring, I would be thinking about signing a player who has strengths where I believe my young players have weaknesses. But I would also want a player whose overall skill set would be similar to the potential of my younger players.
Melton. Established defensive player (for his stage in development at least) but his offense, particularly shooting, is an issue.
Okobo. All around skill set. Good defender. Seems to have the athleticism and skills to be an NBA starting pg, but needs to gain confidence and experience.
Crawford does not lack in confidence or offense. So maybe there is something there. I am not holding my breath though. At 38, a player is on borrowed time.
