He might be the worst coach in recent history in terms of developing/trusting youth. Brenden Dillon is gonna play 23 minutes a night and Logan Stanley & Perfetti will end up in Bones' doghouse the first time they think about doing something other than dump & chase. He's so unbelievably inconsistent with how he treats younger players vs older players in terms of mistakes.
That being said, he does, somehow, get decent results, and I'd think the Jets will be in the playoff hunt next year because of having Hellebuyck back there in Bowness' system.
