There is a difference between the cerebral reaction "I might lose this puck battle because this guy is good" vs. the visceral, primal, reflexive reaction of fear that impairs your ability to perform when a physical threat is bearing down on you. The former may sting your pride a bit until you tell yourself "it's ok, he's pretty good", but the latter carries both the fear of failure and the panic of immediate, serious pain.
Physical intimidation is a real thing. Even if there's no stat for it.
Regarding Mojo, yeah he's got some straight line speed but I doubt he's one of those players coaches gameplan for. That's what we're talking about here, I think: gamechangers. The guys who other players will talk about or just get bug-eyed when facing up one on one because they don't want to be posterized. Mojo didn't posterize anyone. He didn't have that consistent finish of the dangler that would cause players to never want to lose position or let him get a shot off. They probably never thought, even with his speed, "I can't let this guy get by me or it's in the net". He missed it or flubbed around the net too much for that.
