#23 pick for Joseph is a big stretch...
He is a 3rd string point guard playing behind Patty 'Androgynous Chucker' Mills...
I like him as a player because he has balls, but he is a defensive point and not a setup man. We can't close games and we can't stretch the floor even though we shot a zillion 3s last year. Joseph isn't the solution and he definitely isn't worth a 1st round pick. Besides, irony would work out such that San Antonio would probably get Payton with that #23 pick, he would become an All Star in their system, and we would read 'WE TRADED Cory 'nobody remembers this guy' Joseph FOR Efrid 'All-Star' PAYTON!!!' posts in this forum for the next decade. I am not saying that Payton will be an All-Star, but if we make that trade... it would basically be guaranteed that the Spurs would make irony punch us in the balls.
If we really like Joseph, then a second rounder would be enough... Otherwise, they are probably asking too much. He becomes a FA in 2015/16 and he only makes $2 million next year.
