Markstrom for me. The guy is a very developed goalie for his age and that has allowed him to have a greater level of success than normal, but his natural talent is not anything other than normal for an NHL prospect goalie, and his already-refined game leaves less room for improvement than his current abilities would suggest.
I've only watched him a handful of times, but his hips seem stiff and his feet seem slow (by NHL starter standards). But Thomas Vokoun and Craig Anderson don't look to have a ton of the physical talents that you normally look for when you're scouting a goalie either. They get results though, so he could prove me wrong yet.
For those saying Schenn's name, is it a matter of a chink in the armor that you see, or that what people like about his game you just don't see as much of as they do? Let's not just give out names, let's support it with a little bit more of a detailed opinion too. That would make this thread more interesting IMO.
