This is the best I have ever seen him play, hitting harder, getting sacks, fumbles, INTs. He is the complete package, I would put him on par with the best ILBs in the game today.
Since Scott got here, he's taken on much more of a leadership role. I think bringing in Scott might have motivated him to play at new level, for job security. Whenever I see him between snaps, he commands the huddle. He's more vocal, as well as what you mentioned in the OP. He's just playing like a crazy man. Like he's becoming the Ray Lewis of the Jets.
not a chance we could pull that trade off straight up, and I don't think I'd want to give up Harris and picks for Marshall right now considering that leaves us in a bad position to replace Harris. Edit: unless I need sarcasm goggles....
He should make the pro bowl. Bart Scott is still a more recognizable name, but anybody who's been watching Jets games knows which is the better linebacker. Bart Scott infuriates me at least once a game with a terrible effort in the open field, I think getting that big contract has him resting on his laurels a bit. Harris on the other hand has elevated his game, he's the only guy on this defense I ever see laying a big hit on anybody.
Harris has been great freelancing on run defense, and he is very quick to the passer when they put him in a delay blitz, and he is a solid tackler. But... I re-watched a few games last week and he does on occasion make his fair share of arm tackles. He is definitely progressing very quickly in this offense, though.
