Sure, I could have selected another point guard for this spot, but I firmly believe that Chauncey Billups is the fourth-best point guard in the NBA. While Billups ranks just 17th in assists (6.4 per game) this season, he does average 17.7 points per contest, but more importantly, brings a multitude of intangibles to the table that just don't show up in the stat sheet.
For example he is a NBA Finals Champion and MVP. Need more proof? Just take a look at how the Detroit Pistons fell apart after trading him while his new team, the Denver Nuggets, improved immensely by making it to the Western Conference Finals this year, while suddenly taking it upon themselves to start playing actual defense, starting with their new floor leader.
