The thing with most big body forwards is they take longer to develop. Particularly centers. I'm not overly concerned with KK, as he actually looked pretty positive in most of my viewings. Defensively, he isn't a worldbeater, but he was better than I imagined he would be this year. He is physical, aggressive, and can be a net-front guy. We really, really, really need that.
Many players just get better by being in the same role and not on a short leash. Kotka will still have his warts and will take some penalties for being too aggressive. If we recall, he looked really good during his short stint at 2C when half the team got COVID. It's totally within the realm of possibility that Kotkaniemi will be a good #2C for us long term, and it's really likely that he is at least a 3C. His contract pays him like a 3C, so I ain't too worried about the money. He won't get better role models for learning and growing than on Carolina where he can lean on Jordan Staal and Rod Brind'Amour.
I honestly think our best move for the forwards this offseason is to go 1) Aho 2) Staal 3) Kotkaniemi 4) Drury and see how they fall. It is a downgrade from Trocheck, but I just think our money will be better spent on the wing.
