I don't see our center depth as all that great.
Scheifele is easily a top 10 Center in the game right now. But after him we have two 3C's and a 4C. Our center depth is no where near where it was during our playoff run. Lowry looks to have taken another step forward this year but I'm just not sure he will ever hit that 2C level, Little has regressed into a 3C and Rosie is still to inexperienced yet to take on more responsibility.
I'd say Little is middle to lower tier 2nd line center currently, but for a contender that's not enough. Biggest problem with him is that he doesn't seem to fit with guys he is expected to play with, as Wheeler and Scheifele are hip jointed and thus not allowing sane line combinations, like CLW, PLW or ELW. There is nothing wrong with CLP other than it puts the best 5-on-5 goal scorer (by far) to 3rd/4th line. While that kind of fixes that "best 5-on-5 goal scorer" part as nobody can do that 3rd/4th line, that's absolutely horrible asset management.
Scheifele is obvious TOP-10 center in the game, and Lowry is super good 3rd line center. Roslovic has a lot of potential, but has been totally misused this season, so we don't know if he will make it to even a 3rd line center this season. Copp is more than adequate 3rd/4th line center as well.
