I do think he’s capable of playing a solid defensive game when motivated. He’s not a complete liability like an Erik Brannstorm or hell even Karlsson was at his age.
The main concern is his effort level at times. His effort and his laziness is what’s held him back.
His game is nowhere near comparable to Brannstorm. Only thing comparable is size but ASP will likely fill out to be 6’0 and 195-200lbs. He’s already 5’11 at 181lbs at 17. Brannstorm is 5’10 185 at 24.
So like Montour.
