all star point guards dont grow on trees
Eh, I don't know. Point guard is probably the deepest position in the NBA. You've got Rose, Paul, Westbrook, Rondo, Williams, Curry, Irving, Evans, Parker, Nash, Lowry, Lawson, Conley, Holiday, Wall, Rubio, Jennings. You could argue against a few of those but generally that's 15 or so guys who probably could be All Stars. Then you've got guys like Collison, Felton, Teague, Andre Miller, etc.
At this point, you have to try pretty hard not to have a competent NBA point guard. You can't say the same for shooting guard, small forward, or center. Power forward is ridiculously deep as well, which is why a lot of guys who should be 4's are playing the 5.
