His defensive game was better then Myers at that age.
There are issues with mann for sure. My biggest pet peeve with him is shot creation and playmaker. He tends to be too cautious in the offensive zone differing to others too much and if he doesn't fix that then he will be stuck with a high third round grade from me.
His defensive is pretty advanced. He has got good gap control, he knows how to cut off the pass, he can transition the Puck quite well with a good outlet pass. His physical game is great. I know we got recency bias as humans, but if we judge mann and others just off the top prospects game or short tourneys, then we are going to miss out on some good prospects.
