Carlsson has been playing grinder hockey since he came back, getting decent ice time but was scratched once (wasn't due to his play for sure), playing with someone who has 0g in 20 games (now has 1 thanks to Carlsson) 4 pts in 6 games, his skating has gotten better, he looks like he's gotten over his illness, might be 100% now. He reminds me a lot of a less physical Sundin, but he can do it all. If he develops his shot and skating more he'll be maybe the best all round player in the NHL, his top speed and acceleration are both fine, his top speed is good, his balance is good, he's steady on his feet and has a motor, he reads and anticipates plays wonderfully, is able to get his stick in between passes well and often lifts the stick to pickpocket the puck. His agility ideally needs work but he makes up for it very well usually by getting to the puck first, doing what he needs to in 1 move instead of 3, and protecting the puck with his long reach and huge body (seriously he seems to still be growing) all while having great puck handling skills. He forechecks well by having a longer reach to get to pucks first and being very hard to take off the puck once he gets it. Right now he's still exploring his game and trying low percentage things out, but his confidence is so, so refreshing to see, he heads to the middle of the ice like a dog on a bone and drives the net nearly always. He's still a playmaker first by far, which probably works against him right now because of the quality of his teammates, but his shot isn't bad. His skating is his largest weakness but it's underrated, it's not bad, it could just be better, and so much of that is going to come in 1-2 years when his lower body strength improves. He reminds me of Crosby a lot. Just oozes creativity and high IQ that serves him extremely well in all facets of the game.
I look at what Fantilli is doing in the US and I'm impressed. Than I look at Carlsson doing the same things in the SHL with shitty teammates against men and I'm even more impressed.
