The guy has been compared to Chelios and from these few games he has played, that looks like the much better comparison than the Scott Stevens ones.
He hasn't looked for the open ice hit much but has been rather tough and physical along the boards and in front of the net, much like Chelios.
His fighting skills seem to be pretty bad, which is to be expected, much like Chelios's fighting skills are rather weak. That being said, Chelios was always in the middle of the rough stuff and I expect Johnson to be very similar.
He now has a nice rivalry going with Shane Doan, something that's really nice to see from a young defensemen who is supposed to help carry a franchise. He was physical with Doan on Thursday night and was all over him yesterday; his first fight against Carcillo was because JJ leveled Doan behind the net with a borderline late hit about 1:30 before Carcillo came over. On JJ's first shift after the fight, he held the puck in at the point and Doan came over to deliver a bit of a late hit; instead of getting a hit, Doan got a crosscheck near his face.
Johnson would have dropped them immediately with Doan but he didn't want to pick up the instigator and auto suspension/fines that come with it. Shane Doan, knowing that he and Gretzky are exempt from this rule, went ahead and dropped them immediately, catching the rookie off guard. Should have been two for roughing to JJ and the instigator/suspension to Doan. I hate the rule and I'm glad it wasn't called, but that is what should have happened and it's why JJ looked so hapless.
His breakout passes are already better than anyone on the team not named Blake or Visnovsky, and he appears on par with these guys already in that department. He looked great in his defensive reads yesterday, forcing guys wide and behind the net by using his excellent skating. He will be a force on the PP when he's not paired with guys named Modry,Dallman, Heward. or Weaver.
He didn't come in and score any points, let alone the 50 in 5 games some people were expecting. The fact that he's playing on a team whose best defensemen yesterday was Jaroslav Modry speaks volumes though. Drop him on a team with a solid d-corp and give him 20 minutes of ice and I guarantee he would have scored some points this year.
There isn't a prospect in the league that is under more scrutiny or has so many people WANTING him to bust. This isn't me being a homer or anything but I'm sorry: it's not going to happen.
