Miami is a ultra poor example to prove your point...We all know how that team was constructed, 3 #1's from different teams put together. Let's not be silly here...Hayward is not in the same stratosphere as a D-wade or Bosh in terms of NBA worth.
Here's another example of someone grossly overrating Bosh. I have been a huge Hayward fan, but I have to admit he isn't progressing as quick as I thought he would. I still think he can get there, but he currently isn't someone that can continually get you a basket when you need it. I give him a value of 8 mil/year at this point and the reason it's that low is because contract money is coming down because it has to. The very top players (15-30) will command huge dollars, but the salary cap limitations combined with the economy will start to have a very real effect. Hayward is good at everything, and he is smart, but he should have taken the 10 mil if it was ever offered.
