Only a radical—and I mean radical—change in hockey and the way it's played could produce another Bobby Orr; simply put, defensemen are not meant to win Art Ross Trophies.
They sure can, in theory, but in practice only one man has achieved this and he did it twice.
The NHL, like many sports leagues, hands out trophies to more offensive players than defensive players.
Some trophies, like the goal scoring title and the points title, are only a theoretical possibility for a d-man to win them, as in, a defenseman can win an Art Ross, but it'll never happen, especially when that player wins defensive MVP honors.
I'll compare to other sports here: it would be like in the NBA, when a player wins the scoring title and defensive player of the year in the same season, there was in fact a player that did that—Michael Jordan.
So you already can take to heart that Bobby Orr was, I could have just as easily posted his eight consecutive Norris Trophy wins as an unbeatable record as well, but the two Art Ross trophy victories will be forever unmatched.
To give even more insight to the legendary greatness that was Bobby Orr, he won his second Art Ross Trophy playing with one reconstructed knee—it was his fourth last season in the league, his last three were seldom played.
Orr was also fifth in goals that season he won his second Art Ross Trophy.
Now, you might ask, what a forward in the NHL would have to do to somewhat equal the accomplishment?
Well, nothing could really equal the accomplishment.
When Mark Moseley won the NFL League MVP, as a kicker, nothing a RB could do to match that exact accomplishment—for the record, Sergei Fedorov in hockey won the Hart Trophy in ‘93-’94 and the Frank Selke Trophy while scoring 50+ goals.
He did not, however, win the points scoring or goal scoring title that season.
Only one defensive player, since Orr, has led his own team in points: Ray Bourque, ‘86-’87.
Bourque wasn't top three in points scored that season; Bobby Orr came second in points; scored three times, all behind his own teammate, Phil Esposito, who undeniably benefited from Orr's presence.
Bobby Orr was the complete player, not many players can hold that label in any sport—perhaps Marshall Faulk in the NFL, Walter Payton or Babe Ruth in the MLB, however Babe Ruth didn't lead the league in home runs while leading in strikeouts as a pitcher—that would be a Bobby Orr accomplishment.
It's just too much to grasp really.
I could write a 5,000-word essay on how Bobby Orr's two Art Ross trophies are the greatest accomplishment in sports history, but sadly, nobody here would have the time to read it.
To re-iterate, Bobby Orr led the league in points scored twice and was top two in point scored five teams total—no other defenseman has ever been top three in points scored…ever!
