According to a source close to the situation, "nothing" would immediately hold up negotiations between the 76ers and Doug Collins, although it's unlikely a deal will be completed tonight.
As we've reported for the last week, the Sixers have pinpointed Doug Collins as the team's next head coach. According to a source today, that pursuit has escalated to the form of contract negotiations, which is little surprise considering Collins' camp has been kept informed with each step of this process and, recently, has been given the impression that this is Collins' job, that Stefanski has already made the recommendation to owner Ed Snider.
Multiple sources have indicated that Stefanski has not reached out to the other two main candidates: Avery Johnson and Sam Mitchell. Right now, this is Collins' job. If something falls through with negotiations, only then will those other two be brought back into the mix.
For the Sixers and Collins, it's only been a matter of timing: for Collins as he works the Western Conference finals with TNT, and for the Sixers as they navigated the draft lottery and the Flyers' postseason schedule.
