Josh Smith wants max. Although he might have to settle for less. It will be interesting to see what he actually can get. Yes he would help a ton. Although The other Smith (JR) would be a great second option and probably costs a lot less. I remember when the Spurs were trying to get JR on a couple of occasions and even in an interview in New York where I live he told the local press that he was very serious about the Spurs as an option two years ago and it was between New York and them.
Maybe this time he will pick them.
