Gregg Popovich Unsure if He Will Coach the San Antonio Spurs Next Season
“I don’t know the answer,” Popovich said when asked about his plans for
next season in an interview Wednesday night after the Spurs’ 105-101 victory
over the Dallas Mavericks.
Popovich said he and R.C. Buford, San Antonio’s longtime team president,
have periodically discussed the club’s various options after this season.
Popovich说他不知道下一季是否会继续执教，并已经和团队讨论过可能的选项。
“He’ll coach as long as he wants to coach,” Buford said.
马刺总管说Popo自己决定是否要继续执教。
短评或心得：
如果下一季退休，马刺要另外找总教练还是用现在的助教？
顺便问一下，现役第二老的教练是谁？
