This isn't a very frequently asked question. Most of the time it's always Deron Williams or Chris Paul. And ya, those two are the best point guards in the league now. But what about this match up, Tony Parker or Steve Nash?
When trying to decide this, you don't have to worry about age because the question isn't who would you rather have on your team? It's who would you rather have on your team for one season?
Steve Nash is a 2 time MVP and still probably the best passer in the NBA. He can shoot from the outside, take it to the hole, and is a pass first point guard. But he can still make the clutch shot.
Unfortunately, he cannot play defense! This is by far his biggest weakness. The Suns have been criticized the past few years for loading up too much on offense and forgetting about defense. We all know they aren't a good defensive team. Now I'm not saying it is all his fault, because it clearly isn't, but he is a very big reason why they aren't a good defensive team.
Your point guard is your offensive leader, he brings up the ball, makes the plays and pops the majority of the threes. He also is supposed to be a good perimeter defender, which Nash is not.
Nash is a great offensive player, but I would say definitely one of the worst starting guards in the NBA at playing defense. Here are Steve's important stats from last season. 16.9 ppg, 11.1 apg, 3.5 rpg, 0.6 spg, 3.64 tpg and he shot 50.3 percent from the field, 90 percent from the line and 47 percent from the three point line.
Parker on the other hand isn't a great defender, but he is a lot better than Nash. The Spurs have won many championships over the years and Parker has been a big part of their success. Just last season, he helped lead them to the conference finals, which they later lost to Kobe Bryant and the Los Angeles Lakers.
Parker probably isn't as good of an offensive player as Nash, but he can still get it done. He has mastered his little tear drop inside the key which he makes almost every time. He isn't as good of passer as Nash, but is probably a better scorer. Parker is also better at not turning the ball over as he averaged over one turnover less than Nash last season.
His defensive stats aren't fantastic, but hey, neither are Bruce Bowen's. Parker isn't a lock-down defender, but he is good for his size. His stats last season were as follows: 18.8 ppg, 6 apg, 3.2 rpg, 0.8 spg, 2.38 tpg and 49.4 percent from the field. Parker isn't nearly as good at free throw shooting or three point shooting as he shot 20 percent less then Nash did in both of those areas.
Both of these players are two of the best point guards in the league and you could not make a wrong decision with either one of them. For me it is truly a toss up. If I had to chose I would probably take Parker just because of his defensive ability, but I can't say that is a definite choice. It totally depends on who else is on your team, with Amare Stoudemire, Dwight Howard or Tyson Chandler I'd pick Nash, but in a controlled offense like the Spurs I'd pick Parker.
