Triangle culture is what has brought this up. Fisher also seems to have an interesting relationship with Melo, in that they don't seem very close like he and Woodson were, but he pushes Melo's buttons in the media and on the court in a way Woodson never could. Fisher has called Melo out early in the season a few times for his defensive effort, passing the ball etc. Melo has responded.
I give Melo credit, but I don't believe for a second that Melo would be doing this without Fisher and the Triangle culture that's trying to be enforced on the team. It's about teamwork, ball movement, player movement. Melo has jumped on the wagon. As season's start he wasn't sure what he could do outside of scoring. Now he knows he can be great even without scoring, and he's doing it again and again.
The point forward, higher defensive/boards version of Melo can average 20 points, and I'd call him a MVP caliber player vs the 27-28 points a night Melo who doesn't play as much defense or pass who I would call more of a top 20 player. He's playing at a level even an all time great like Kobe would be proud of. I'm not saying he's reached that level, but he's playing in a balanced all around way that some of the great wings in the Triangle have. If he can keep this up for 2-3 years, he will cement his legacy much higher than he would have had he kept playing the other way.
I'll take 21/8/5 Melo over 28/7/3 Melo any day of the week.
