If the top 5 is just based on the 2012-2013 season and nothing more.
My top 5 would be...
1. Lebron James
2. Kevin Durant
3. Chris Paul
4. Carmelo Anthony
5. James Harden
HM: Russell Westbrook
The first three should be fairly obvious
Melo and Harden is a tough choice for me honestly but I went with Melo primarily because he led his Knicks to a better record and because he won the scoring title. Harden is great and I certainly would rather have Harden on my team opposed to Melo, but I'm not sure if I could say he had a better season than Melo did this season.
I think the playoffs will end up defining it all. I don't think Harden will have a very good post-season. He looks unbelievable tired right now from carrying this Rockets team all season long and this is mainly Mchale's fault for overutilizing him to death and failing to utilize his other pieces like Jeremy Lin. Of course, Carmelo Anthony could easily choke in the post-season as well since he is not a very good post-season performer himself.
It is very possible that if Westbrook has a dominating post-season performance that he leapfrogs over both of them in the rankings. Westbrook is the popular pick for the All-NBA First team guard and I know most RealGMers will be ticked off when they see that.
I think Dwyane Wade is a better overall player than both Melo and Harden currently are, but he has been inconsistent this season due to coasting, injuries, and so fourth, so I can't put him above either or even Westbrook for that matter.
I'm guessing the point of this thread and project is to talk about the best players of the season, not the best players overall, otherwise I feel like some of these lists would be very different.
