Ok, so Joseph's top speed was 22.85 last year, and we know that guys like Norris (22.95), Stutzle (23.47), Ostapchuk (22.92) and Gregor (22.97) all had higher top speeds last year, but how about busts over 22 mph, that should give you an idea how much these guys use their speed in game
Joseph 9 times over 22 mph
Norris 12 times,
Stutzle 23,
Ostapchuk 2 (in 7 games)
Gregor 15
Honestly, I feel like Joseph's speed is very good, but it's like a fishing story, it gets bigger every time we talk about it. Everybody seemed to want that element Formenton brought and just decided, well this new guy is a pretty fast 3rd liner, and transferred that reputation over to him, but when you look at the fastest guys in the league, Joseph doesn't really hold up
Miles Wood : 23.88 max, over 22mph 45 times
Formenton (2022): 24.21 max, 31 times
Point: 23.46, 43 times
MacKinnon: 24.05, 118 times
McDavid: 24.19, 66 times
McLeod: 23.82, 27 times
Tippett 24.21, 46 times
Joseph is quick, and he's fast, certainly well above average in both, but he is not uniquely fast the way some portray him, that's fantasy.
