So I'm pretty confident in the 6-10 month range they've put out there. But, being completely honest, its not my forte. I'm just putting out there what I've learned at conferences and seminars.
But the names you listed? Those guys had degenerative conditions. Its not at all the same. I'd advise that you read MT2s take on all this, as he details the difference between Bogut's injury/surgery and those guys'.
As for rushing him back, you have to test the ankle at some point. A lot of the times players can heal while playing, especially at what we call at the office the POHNR (point of healing no return) where playing on the ankle won't really affect it's healing.
