Who do you think is the best PG in the NBA? + Who will be the best in the future?

To me it is Deron Williams he has been the driving force of a Utah team that consistently makes the playoffs and wins at least one series. He has great scoring and ist numbers, his size and strength make him an incredibly difficult cover for anyone in the league, he plays solid defense and can hit threes accurately. Rondo can't shoot as well and is not as good with his decision making, Rose is more of a scoring point guard but still can't shoot like Deron, Harris isn't even in the discussion, Nash is too old and plays zero defense, Curry is just a scorer, Jennings is very talented but makes too many mistakes, Evans and Wall are too young and are both scoring point guards instead of playmakes. Paul has the best arguement but he has only had one year where he took a team to the conference finals and hasn't done much else.
