Here's an interesting tidbit I just ran across in a Khan article about Nestrasil...
"[Nestrasil] would have been buried further down the depth chart once Pavel Datsyuk and Weiss return from injuries and after the club promotes top prospect Anthony Mantha, which it will likely do if he produces in the AHL the next few weeks."
The bolded part is interesting because until very recently Khan had repeatedly taken the stance that as a result of his injury (and lost training camp), it would be unlikely that Mantha would crack Detroit's roster this season. This sounds almost definitive. As in, someone told Khan (off the record) that he'll be promoted if he plays well out of the game. Usually Khan's good about acknowledging when he's speculating. That doesn't seem to be the case here.
I'm not seeing it, Pulu has to be the next call up with how he's producing.
