Arnott isn't nearly as physical as you would be lead to believe.
He's got the Jeff O'Neil Syndrome where a good playoff run made everyone believe he's a gritty, hard nosed team player.
He's no different than Chris Gratton in regards to using his size to score. And at least Chris Gratton fights, Arnotts only fight last year was because he was jumped.
He's not a tough player by any means.
BTW: I'd want neither player on my team.
Jason Arnott is a different player than Jeff O'Neill in terms of physical abilities. Jason Arnott is one of the most gifted players in the NHL, but his inconsistency stops him from putting up amazing statistics. This year he was fairly consistent for his doing, he's simply one of the most dominating players in the world when he's on, hitting everything in sight, relying on his size and skill to get to the goal. Chris Gratton is a very poor comparison. Jason Arnott is a physical presence for at least 60% of the games, Chris Gratton is not.
Fighting doesn't indicate whether someone is tough or not either. Derian Hatcher rarely fights anymore, yet he's as tough as they come. Same with Jeremy Roenick.
And that one fight he had he wasn't the one being jumped, he was the one jumping in, saving a teammate. He jumped Eric Cairns after Cairns started pounding Steve Ott.
