Skinner? He was 29-14 with a .916 save pct. in his rookie season and even showed some promise the prior season while stacking good seasons in Bakersfield. Skinner was on a real upward trajectory until the playoffs hit, which is tough on most rookies, and he hasn't recovered since. Hell, look at guys like Oettinger and Helleybuck who got torched in the playoffs last season.
There's a baseline to work with with Skinner but his confidence is in the toilet now. Finding a real goalie coach would be a good start.
