We're not a bottom 5 team anymore. And we shouldn't be rushing prospects.
There's nothing wrong with giving him a good year and a half (or more) in the AHL before full time duty in the NHL. In the long run, it's the best thing for him.
The best thing for him is to monitor where he's at and have him progress based on merit, not artificial timelines
He's an older prospect relative to his draft class, you look at a guy like Luke Hughes, who is on the opposite side of the age spectrum and he was full time by his 20th birthday, Yakemchuk will be 20 to start next season. Similarly, Sieder was full time in Detroit as a 20 yr old. Byram joined a contender in Colorado and played one yr of junior after being drafted before cracking the NHL club though injuries limited his games played
There's no hard and fast rule for what's best for a player. His play will dictate what's best for him.
