I remember the year the Ducks won the cup, Pronger and Niedermayer played about 30 minutes a game.
I don't think Ryan Suter ever came off the ice when he played for Minny.
These guys played a different style than Cale though and the NHL didn't require as much skating in their day.
Niedermayer and Suter played a smooth skating style like Toews that probably didn't raise their heart rates much. Big guys like Pronger could play a ton back then because they didn't have to move much.
Cale has a power/quick twitch element to his style, and skates close to flat out in both the D zone and the O zone every shift. An underrated part of all of this is how hard he battles physically in the D zone, while still hustling offensively. Cale turns 27 in October, he can probably only play the way he plays, 30 mins a game for so long.
He's been able to play this much so far, but it only works until it doesn't. Then you look back and say, "was it really important for me to play him 30 minutes in a game we weren't winning in January?"
I like Bednar and want him to stick around, but that's what he did in that Hawks game Jan 8. Played him 29:34 in a 3-1 game, in the first game of a back to back, where it was pretty obvious they didn't have it in them to come back.
To make it even more nonsensical, Bednar kept Cale out on the ice for the last 4:30 of that game. There were a couple whistles, but Cale was hunched over visibly huffing and puffing at the blue line not even trying to get to loose pucks, because he was so tired. Even kept him out the last 10 seconds after a whistle. Like why?
