Sestito is just nowhere near the same caliber as Orr, let alone the real tough guns.
I've boxed as well, and can tell you when a guy is a "proper" fighter, and one who learnt just to do what he could to make the show.
I can tell you that I grew up with Riley Cote, and when he was off from AAA -> Maj Jr for Prince Albert, he was not at all a fighter. In AAA, he was a league leader and had a pro-level shot.
in the dub:
1998–99 Prince Albert Raiders WHL 37 3 2 5 63 9 0 0 0 9
1999–00 Prince Albert Raiders WHL 67 6 7 13 71 3 1 0 1 2
2000–01 Prince Albert Raiders WHL 64 17 35 52 114 — — — — —
2001–02 Prince Albert Raiders WHL 67 28 23 51 134
he was a "contributing" player in the western hockey league, learnt to be "tough" but went undrafted.
So, he still wanted to follow his dream, and made it to the show, the only way he could.
That being said, he learnt to fight with my old Boxing coach, Simon Mircea. Cote' was alright, and he learnt to do what he needed to, to fight on the ice.
But how good of a "fighter" was he? I'll put it this way, while he was away play Mj Jr, I became a div golden glove, and there would be no way on "dry-land" that he could be able to keep up.
I'm sure these days he's stronger than hell and has a ridiculous pain tolerance, but he was just wasn't a "natural" fighter.
However based on my observations, being a boxer:
Rypien was perhaps the best technical fighter, regardless of weight class, to ever touch the ICE. I liked that he could actually log real time in the game, as an energy player and answer the bell.
Next?
Eric Goddard... you can tell he knows how to throw them, and was quite effective
Then... currently I'd say its McGratten & finally Macintyre (who's wife was my Boss lol... she's a IT/SAP VP)
