KG and TD. Growing up, my favorite individual matchup to watch was those two, they'd both put up huge numbers but in such a different fashion, it was awesome to watch. KG is my favorite player, but I've always had a great amount of respect for TDs game.
After those two, I think I'll miss Dirk the most. It's so fun to watch him toy with defenders. His and Nash's skill level is just off the charts, and they beat you with their skill, angles, and smarts.
