There is literally not a single shred of evidence to support either of these. But I suppose utterly incorrect opinions generally would be unpopular.
I love the reactions to these posts. It's a thread about unpopular opinions. OBVIOUSLY most people will disagree and I'm aware of that. There is, however, PLENTY of evidence. You just don't want to notice it. Dubinsky (the younger player) out-produced Callahan every year until this past year. Callahan has only one thing going for him that Dubinsky doesn't--his confidence level. Dubinsky gets trapped inside his own head during a slump. Callahan doesn't.
Frankly, most of the things people ranted about regarding Dubinsky (doesn't know what kind of player he is, inconsistent, etc) apply FAR more to Cally than they did to Dubi. Dubinsky's problem was that he would back off and defer too much when his confidence was down. Callahan is the one who seems to think he's a skill player instead of a grinder from time to time. Again, how many times did Cally pull that no-look pass to nowhere last year? That nonsense resulted (often) in goals against, because he would give up odd-man rushes to the other team.
I LOVE Callahan when he plays his game. I get completely frustrated by him when he doesn't (and he had far too many games last year, particularly in the playoffs, where he was trying to be Ryan McFancypants instead of Ryan Mother****ing Callahan). I think Dubinsky kept him honest/grounded.
I also disagree with the poster who said that Cally plays well with Stepan and Kreider. There isn't a big enough sample size for Kreider, and Callahan has never played well with Stepan.
