Some general comments on training camp...
I watch the pre-season games... and it's a chop suey mix of players that you know will never make the NHL, vets with 5 months of rust in their bodies and prospects who are busting their asses to make it and "overplaying" in some situations in order to make a good impression.
You have forward lines and d-pairings that have never played together and you throw them in there and expect to assess them vs other teams with the same mish-mash of prospects/vets and no-hopers.
I think the first half of training camp is pretty much a waste really to be honest... yes it helps players shake the rust off but as far as evaluating skills, it's pretty much useless. Too much randomness in the rosters... no real systems in place including nothing concrete on PP and PK structures... even the new coaches are likely trying to all get on the same page with their coaching methods and systems as well.
If the camp was basically comprised of say 25-30 players with actual legit chances to make the team from Day 1... at least that would allow some slightly more meaningful assessments as you'd have everyone (very roughly) at the same levels so at least you could run lines and work on structure and PK/PP systems could be worked on earlier... which would allow for more comparing and contrasting to see which players might actually help the team the most in certain situations.
I know you have to allow everyone their slice of camp to give everyone that feeling that they are a valued member of the org... but realistically it's not until much later in camp that much of anything useful starts to actually occur in terms of building chemistry and getting solid PK/PP units going and teaching the systems that the team will be using.
3 goalies
9 dmen
16 forwards
That's probably an ideal camp.
You know you'll have to cut 1 goalie... 2 dmen and 2 forwards and that makes for a much better environment to actually teach systems and actually get the team bonded and ready for the season while still having a little healthy competition in camp for positions.
63 players in camp (some teams have 70+) is pretty meaningless in terms of actually getting much done until it's whittled down to that 25-30 number anyway.
