Catton isn't really look down upon because of his size I would say. I imagine he's less favourable because you have another player who's a good player, skilled, but a player that won't be hard to play against.
He's a guy who, at times can make it hard with his skill and keeping it away, but when games become tighter I'm speaking for others in that he might not be able to break through and use what he has to make the game more difficult in the playoffs.
Demidov, who's projected to be more skilled and could be that game breaker.
Lindstrom, the conservative response is likely a 60-70 point player who's physical. If he's not scoring, he's (hopefully) out there being a physical specimen on the other team and making the other team hate him.
