in what way? does he need to pat them on the bum and tell them they're special? These are professional athletes if they can't get motivated to play, especially when they're trying to get out of slump, then that sounds like a them problem, not a him problem
I'm not defending Holland, he needs to figure this shit out ASAP, I'm saying people are massively overreacting to a stretch of hockey that can be chalked up to poor goaltending.
other people have cited that they were winning on the backs of Mcdavid and Draisaitl's ridiculous pace to start the year, and the almost 50% PP effectiveness, while that isn't wrong, all that really did is gloss over the fact that the REAL problem is and always was below average goaltending. if the Oilers would have had a consistent .920 save percentage for the whole season, which isn't outlandish by any means, they are STILL a top 5 team in winning percentage.
coaching only does so much for a team, but a weak goalie not only does the obvious like letting in bad goals, it is the most damaging thing to a teams psyche. Players start to play different in front of that goalie, trying not to make any mistakes, while at the same time trying to sore 6 goals a game. The players know any defensive mistake is in the back of the net and they'll have to score 5+ just to stay in the game. When you can't trust your goalie to make a save it completely alters how you play your game, you start taking stupid risks offensively and gripping your stick to tight defensively.
it's like a bad starting pitcher in baseball, players start to swing for the fences at every at bat just to try and make up for the bad runs the pitcher has allowed, unfortunately for hockey, they don't have bullpens of 7 goalies they can bring in to play 8 or 9 minutes at a time.
