Yeah, I think it's getting to the point where the players are too spoiled. Maybe it's because of the number of teams in the league, or any of the changes that the NBA has made, but the players today (while probably more athletic than those past) are mostly mentally softer.
I really don't get how Melo can even consider asking for a trade after the success he's had in Denver. And in the same vein, LeBron as well. The Cavs had the best record the past couple of years, Shaq was an expiring, and had LeBron re-signed, I'm pretty sure other FAs would've come to him. Instead, we had to see "The Decision"
