Okay, moving on from being disappointed we didn't nab Fantilli, I'm still very excited about Carlsson, who still projects to be a game-changer for this franchise.
Carlsson's skating is brought up as a bit of a negative for him but as I mentioned before he reminds me a lot of Rantanen (also Draisaitl) especially when it comes to skating, so I really don't think it's going to be much of an issue for him, especially as his stride gets more powerful. He's got quick feet on his initial crossovers which allows him to get into stride pretty quickly (much like Mikko) and his ability to process the game allows him to get those feet moving rapidly in the right direction.
I think his shot is the area he needs to develop the most, I like his shot in close and his snapshot from mid-range when he has time but if he wants to take full advantage of his toolkit he's going to need to develop his one-timer and work on the quickness of his release. Part of what makes Draisaitl and Rantanen so effective is you can't cheat, they can beat you from anywhere with their shot or playmaking abilities. It also makes them much more effective on the give-and-go with short passes (which Leo is already great at initiating) because they're able to take a quick pass back and bury the puck from any angle on the one-timer.
I see a bit of the Kopitar comparison since Leo should be able to play that puck-possession game with the elite hockey sense but I don't think Leo is ever going to have Kopitar's defensive acumen and I don't think he's ever going to create offense from defensive plays the way Kopitar does, which is why I think he should model his game after Leon, Mikko, and Malkin rangey players who love to dangle and can beat you on the cycle or the rush.
All-in-all I'm excited for this player and his development. I also don't think he should be in the SHL next season. He's already played 2 full seasons over there and I believe it would be wise to get him onto the smaller ice surface. If he blows the doors off he can play the entire season in the NHL but more likely he should spend most of his time in the AHL with some time in the NHL.
Good luck, Leo! Prove us Fantilli folk wrong!
