Paired with acquisitions via free agency and trades, 2-3 years with smart drafting (regardless of draft position) should provide plenty of time to show that things are AT LEAST heading in the right direction. Completing the actual rebuild may take a little longer, but that's also why I wouldn't mind giving Vivek 3 years MAX. If, during that 3-year period, the team is at least showing signs of heading in the right direction, then we ride the ship. If, during that 3-year period, the dude shows the same amount of ineptitude as he's shown during the reload, then I'll be asking for his head.
Then we have gone through 2 rebuilds the past 16 years.

Both times the rebuild was derailed early by poor decisions.
For the past 3 years we've been in the best position in 20 years. How would trading everyone and starting over be any different?
