That's a good point. But if Nurse is clearly on the cusp of NHL ready why not give him a month or two with the team. Play a few NHL games, get a nice paycheque before going back to the CHL where he can use the new skills and continue to build on what the NHL staff tell him he needs to work on.
Where do you slot him in, though? It's not like we necessarily have a plug (yet) on D. Our two new guys should be meshing with the team and finding their groove here, so you don't want them sitting for Nurse. You can't sit the captain so a prospect can get his 9 games. Petry gets dumped on a lot here, but he's a steady presence, and Marincin was one of our best defensemen last year. Schultz also needs to continue his development, he can't start the season sitting for 9 games. This is where he needs to start becoming a better defenseman.
Only way I see it is if someone gets injured during exhibitions/training camp, or if Marincin hasn't come prepared. Marincin could then start in the AHL, and whoever is playing better between him and Klef could replace Nurse after his 9.
