Patrick Ewing remembers the challenges of going from an NBA player directly to an assistant coach with the Wizards in the same year (2002). So he knows it's going to be much more taxing for Jason Kidd to transition to a head coaching role with the Nets. "It's a big difference, especially going to head coach," Ewing said on ESPN New York 98.7 FM radio on Thursday. "It was a big difference for me going from a player to an assistant coach when I did it in Washington. When you're a player, you don't realize how much time commitment that being a coach is. ... But then going to being a head coach, the buck stops there with him. That's where all the heat's going to be going."
