I have wondered this a bit, and there is this narrative out there that Stevie is afraid to promote the kids, but he called up Seider at age 20. He called up Kasper at 18. Mazur was a bit older, 22, when he got the call. Maybe Stevie calls up young players when they are good enough to beat out proven NHL players (or “washed up veterans” as some call them).
I have no doubt that the locker room wanted these kids. McClellan wanted these kids. That made it easy for Stevie to call them up. But I don’t believe for a second that Stevie is afraid to call up the kids when they are ready.
