Typically, that’s not how the term “hands” are perceived, which is why you’re getting pushback. Hands is typically viewed as puck handling and deception. That’s not what Cates is good at, and I think if you asked Cates if he had the best hands on the team, he would laugh.
He’s good puck protection, very good in fact. But he doesn’t have the soft touch that’s indicative of ‘hands’.
I see deception and vision as different skills than "hands." More "playmaking."
Michkov has great hands, see how hard it is to separate him from the puck, what makes him exceptional is he combines those hands with the other skills.
Hands to me is "puck control", whether handling the puck in a crowd or skating with the puck under control (see how many Flyers flub the puck when they try to accelerate down the ice) or smoothly catching a pass without it bouncing off your stick.
Cates has really good hands (by my definition), his problem was he was coached to be defense first in college and lacked confidence in his offense skills, as Torts says, he'd dump the puck rather than hold it and wait for something to open up - and good hands buys you that extra second. Since he returned to center he's playing with a lot more confidence offensively.
As far as Torts as the defense obsessed HC, he's been pushing Cates to be more aggressive on offense. He's said part of development is players learning to do things they're not comfortable doing.
