The connection between Jax and the Spurs transcends anything he could have accomplished there. He will be an improvement over Jefferson... immediately.
The glory days of the "We Believe" era for Jax were all wiped out for me personally the way he handled his out of GSW. Wish him the best of luck with the Spurs but I'll take Jefferson any day over what Captain Jack would have done to this new young GSW team.
In short, win win for both teams! LOL
