That would be an intentional misleading of the fans. Masai and Lieweke made it very clear during the offseason and it was meant in the here and now. 7-11 is a death bed in the NBA.
If he did come back and say he didn't give a timeframe, I would personally feel the BC vibe creeping in again. Talking out of your mouth but ain't sayin' nuthin. Saying you want to 'contend' but really saying you are 'content'.
