I'm not one to debate if this era's players are better trained, bigger, ya-da-ya-da than were those who came before them.
However, the generalization that "players" back in Orr's era were so horrible or words to that effect are lazy, disrespectful and plain wrong.
Let's see. During the period of 1966-1978, Orr's career, roughyl speaking, such horrible players as Bobby Clarke, Bryan Trottier, Marcell Dionne, Guy Lafleur, and Bobby Hull, just to name a few, all toiled. All Hall of Famers. All among the greatest this game has ever seen.
To read some geniuses generalize, and categorize these players as anything other than great - then and now - is insufferable.
