There have been more than enough quotes from Fletcher & Flahr, plus his extraordinarily sheltered zone starts in the NHL by AV, to explain why Frost isn’t up right now.
Especially to explain why he wasn’t the callup on the road against Pittsburgh with the Pens having last change.
His play away from the puck & his pace haven’t been consistent enough in the AHL or NHL. He’s still working on paying attention to details & breaking bad habits caused by being used to dominating weaker competition.
They also don’t want to call him up just to play 7 minutes on the 4th line when he can be working on his game in important minutes in the A.
It’s not like Fletcher has shown to be reluctant to call up kids. Quite the opposite. Frost got one look. And he’ll likely get another one before the season is out.
I’ll add that with 0 goals & 2 assists in his last 5 AHL games, it’s not like he was banging the door down for a callup tomorrow.
