Now after looking at the NBA during the last few seasons. We realize while there's tons of point guards in this league, they don't necessarily guarantee perfect success. It seems unlike Magic, Stockton time etc. where they played a big impact on their teams, the point guards of today need more help.
In the case of Miami, the lack of a point guard killed them against Dallas. So they decided to make James the point guard, and Chalmers the extra shooter next to Wade. Worked out for them so far.
In the case of Indiana, they tried to make off-guards and shooting guards adapt the role but we saw how terrible that was against the Heat. Ridiculous # of turnovers as Hill and Augustin couldn't even pass the freaking ball.
Some undersized shooting guards like Westbrook and Holiday have found success at the position although playing out of position but probably because of their size as undersized shooting guards which gives them excellent mobility, and their passing ability is not garbage like some of the off-guards.
Some guys like Jeremy Lin are raw talent but they're capable of too many turnovers. Some like Ty Lawson have great nights but their size leaves them vulnerable.
But with the way things are going. We're less likely to see ugly basketball in the case of undersized shooting guards like Derrick Fisher who can't create anything, and are more likely to see 1 on 1 duels between top tier point guards, and also perhaps some hope for the future to see ball handlers/point-forwards make a return to the game. LeBron James has been doing an excellent job as a point-forward. Even chasing down point guards himself. Dirk also played a bit of the position during his championship run feeding the likes of Kidd, Stevenson, Terry on the offensive end etc.
Hope to see more point-forwards and top tier point guards in play. Guys like Larry Bird, Magic Johnson, Scottie Pippen, Ron Harper, and Michael Jordan gave evidence that you don't have to be 5'11"-6'3" to make it work as a ball handler.
