That's what I'd like to see: let Mattias get some A experience before anointing him the 2nd or 3rd line center. We saw Kreps improve over the season & he can still grow. I just hate the idea of forcing someone into a role they are not ready for. If JM thinks Mattias is ready for the NHL, then it certainly wouldn't hurt to have him work his way up through the A first. Same for Frolik.
Kind of like what happened with Booth - got a call up & played his way onto the 2nd line with hard work & production.
Matthias isn't going to make the team by default. Right now, we've got enough forward to ice 4 lines. He's only going to make the team if he comes to camp and outplays several guys, which IMO is a moot point because I think he's going to do just that.
Off topic, but what's the weather like in the 2nd week of September in Denver? My cousin is getting married so I'll be out there around that time.
