There aren't many shooting guards as talented than Rider. Jimmy Jackson is a great scorer as well. Don't be misled by JJ's stats this year. He can put points up on the board when need be. Those two are fine players.
Rider is a head case, a malcontent and an accident waiting to happen.
But Pete Babcock must have been dying watching Allan Houston and Latrell Sprewell kill the Hawks with their speed and athleticism. They needed to get younger and faster. First they unloaded veteran point guard Mookie Blaylock and replaced him with highly touted rookie point guard Jason Terry, from Arizona. Then he made this trade. Jackson and Rider are very athletic and both are exceptional scorers, when they are hot.
