I think he can be a good player, but I also think it's reasonable to be skeptical about his upside. He's one year older than Farabee and look how much further Farabee already is in his development.
It sucks for him that he got hurt this year because the way Patrick is playing this was his opportunity to earn a full time spot.
Can't compare Farabee and Frost. Apples and oranges.
Farabee has a bigger frame, more natural strength, better hockey IQ.
Frost was coming on before he got injured, late maturing both physically and in terms of hockey instincts, especially converting his raw speed into game speed.
People get impatient, Frost will be 22 next year, same age Guentzel hit the NHL. Won't surprise me if he has a similar breakout season.
