By solid you mean up and down like a toilet seat? This game makes up for the Capitals game, where we saw an actual theft by a goalie. He got lucky in the Colorado game that the Oilers are an offensive wagon.
You did mention the defense. They played fine against the Kings, they dominated most of the game against the Bruins.
Skinner is just lucky that the Oilers are a good offensively as they are. His top end talent is 100% there, his problem has always been consistency. They don't need .940 most nights, but they can't make up for his .800 nights.
Like I said, he's either very good or very bad, there's nothing in between.
