Hedo is a unique talent that requires ball domination to be effective. As much as people complain about RJ, Hedo as well just did not fit in the Spurs system. And his performance in the playoffs most definitely sealed his fate. If I remember he signed for something around 5 mil a year with the Magic. That season as well the Spurs signed Brent Barry for about 4.2 million a year; which worked out well for them.
If anything Hedo's 2007-2008 season with the Magic was a bit of a fluke, only once previously had he shot 45%+.
With regards to SJax, he turned down a
3 year $10 million contract offer from the Spurs. So no it wasn't lower than vet minimum. Financially it turned out well for him after it was all said and done.
