How is it a horrible comparison? There is a stigma in the NFL that you have to be at least 6'2" to be a successful QB. A similar stigma exists in the NHL. There are certain players where height doesn't matter. I am not willing to say that Enroth will never be a quality goalie because of his height. Especially after the way he finished the season. You seriously think there is no chance a shorter goalie could be a great goalie? It is extremely short sighted (no pun intended) to dismiss Enroth because of his height. Maybe he doesn't take up as much of the net, but isn't possible that he can rebound more quickly than larger goalies. Dismissing Enroth because he is short is just dumb.
I believe the people that don't think he can be a starter; is not dismissing him because of his height, but because of his play in net. Height does make a difference in the league today. When the league was mostly stand up goaltending I would say the height shouldn't be a problem, but with the way players shoot nowadays, and how accurate they are, taking as much space and being very quick is turning into a must now. The height of goalies also affects their ability to see through, and around, screens.
When you watch Enroth, his biggest weakness is his 5 hole. For a goalie his height, that should be a strength(takes less time to go down, shorter legs should lead to smaller 5 hole). His weakness should be up above the shoulders and down low past the legs. The fact he is a butterfly goalie, doesn't go well for saving shots that are high.
He does have amazing quickness, and his calm demeanor is a positive to have in goalies. He comes off as a good guy in the locker room, and the players seem to play better and player better together when he is in the net.
I would rather have him in the backup role IMO. But if you're in a rebuilding phase, I guess its best to see where guys are so you can move forward with or without them.
