On Kooch ... yeah, that was pretty miserable. He's obviously fighting the puck and reacting late, and when he's off his game then all of his quirks turn into huge liabilities. Does that mean he's going to be terrible forever? No. This is a part of the package, and he'll get his game back eventually. He's got to play through it, though ... so sitting him would be counter-productive for a team that really doesn't have much to play for in terms of playoff position. It's probably better just to stick to the script and let it play out. Then he'll probably be on the upswing by the post season.
That said, this is why I'm OVER this goalie tandem. You can't trust one of them to stay healthy for more than a month and you can't trust the other not to randomly implode and start barfing up goals willy nilly. I don't care if they bring one of them back, but bringing both back would be patently stupid.
And on a positive note, we got the Tony D (aka The Italian) special last night, just not quite the obviously humiliating version. On that shorty that Jarvis scored, you could see both Aho and Jarvy light up when they saw who was back defending. Jarvis 100% diverted his path to create a bit of width to isolate DeAngelo one on one, knowing full well that he'd either play it too soft or too aggressive. Tony never gapped up and left Jarvis an opening to bomb one, but if he had closed the gap you know full well that Jarvis would have just juked and gone around him. It's lose/lose with that guy as the only defender back.
