I agree. The best player will be the best player.
But for the sake of this topic's argument, let's take a look at the 14 teams that didn't make the playoffs last season and their point guards.
From the East:
New York
PGs = Garbage. Starbury/Crawford only put up numbers, not wins.
New Jersey
I like Devin Harris, I think he could be good one day, but he isn't a true PG yet. He was also surrounded by some pretty horrible talent, so it wasn't entirely his fault.
Indiana
Tinsley. Shot 38% from the field, 28% from the arc and averaged over 3.33 topg. The trade for TJ Ford was made for a reason.
Chicago
With Derrick Rose being drafted, Hinrich is moving to the combo guard position. No true PG on last season's team.
Milwaukee
Mo Williams is in the same mold as a Stephon Marbury. Fantasy beast but no playoffs in the East, even with Andrew Bogut, Michael Redd, and Charlie Villanueva as sidekicks.
Charlotte
Can't really explain this one here. Ray Felton is a good PG, but does have work to do on his 41% FG shooting and 28% 3 point shooting (he shot 2.5 threes a game, too). Another thing worth noting is that the Bobcats had good players at every other position (JRich, Gerald Wallace, Emeka Okafor) but still couldn't make the playoffs.
Miami
Chris Quinn played in 60 games at point guard. Don't really need to say much else there.
In the West:
Portland
They finished .500 and had solid PG play from Steve Blake. Would have made the playoffs in the east.
Minnesota
Randy Foye and Sebastian Telfair are the types of guys that could be good down the road, but right now aren't to that point. Foye is a combo guard and Telfair is a guy that would be coming off the bench on most other teams.
Seattle
Earl Watson and Luke Ridnour. Guys that would be bench players on most teams, and in fact, their starting PG, Earl Watson, was a bench player the majority of his career.
Golden State
48 win team that somehow didn't make the playoffs. Baron Davis is one of the best point guards in the league.
Sacramento
Beno Udrih. Not a bad point guard, and was good enough to take his team to 38 wins, which would have been enough to make the Eastern playoffs.
LA Clippers
Sam Cassell was starting for them for about 30 games, averaging 4.7 apg. Next highest after that? Tim Thomas at 2.7 apg. Baron will be the most appreciated player in Hollywood in 2009.
Memphis
Young and inexperienced Mike Conley, Jr. and Kyle Lowry. Down the road I see these two being pretty good, but last year it was a lot to expect from a 19/20 year old MC Jr. to take this team anywhere.
Any team without 37 wins last year had below average (or terrible) PGs at the helm, even though many of them had good big men and good swing men.
Also, taking a look at the 16 teams that did make the playoffs, there isn't one with a bad PG. The exceptions are the Cavs and Nuggets, where guys like Lebron and Iverson would handle the majority of the ballhandling and distributing duties, thus taking over the job of a PG even if it wasn't their stated position.
