Is coaching to blame for some of that? Maybe. Let's go ahead and say yes. I don't know that coaching explains why all 5 guys on the ice get caught staring at the puck and don't pay attention to someone sneaking down the wing for back-door tap-in. Or why guys just mindlessly fling the puck around the defensive zone under pressure. Or guys flub easy passes, or have time and aren't under pressure, look up ice with 2 safe options that would be a 45-foot pass and try to go for the 125-foot pass and put it on the tape of the opposing guy in the middle of the ice who doesn't have anyone within 15 feet of him. I'd like to think if you've been playing defense for 10-12 years or so, by the time you get to the NHL you have an idea that neither of those things are something you should be doing. If you're Faulk, Parayko, Leddy and Krug, you really shouldn't be doing that - and yet, we've seen it happen way too often.
