Look i agree that turtling has failed and it's not a good strategy, but i also don't think we have the offesnive horses to hem a team in and put pressure on them when we have the lead. Instead I could totally see the team doing that, making a bad turnover and having a goal go in the other way.
I know this isn't an apples-apples situation, but remember that game against Vegas where Stone expertly stripped Celebrini of the puck and scored an ENG (maybe Hertl actually shot it)? That has such a high risk of happening if we keep pushing for offense in the 3rd while holding a lead. I dont think Graf, Smith, Mukh, or any of the young guys (save macklin) could bounce back from trying to make an offensive play and costing the team goals if it happened over and over again. We're simply not good enough to not make mistakes, and definitely not good enough to overcome mistakes in game, so i understand trying to limit them by turtling.
You're right that trying the same thing over and over is futile, but I also don't think there is another viable option. Sure, its worth trying, but we shouldn't then be surprised if the team gets its teeth kicked in. If that's the perceived outcome, which again I really think it is, a 2-1 OT loss is better than a 5-2 loss.
That is really a philosophical question though about what you think is more detrimental to the mental state of our younger players.
What is worse, trying to win the game by playing your game, playing your lines as usual, with the risk that one of our younger players makes a mistake that costs us a win while trying to generate offense.
Or dont play the young players much, minimizing that risk, but also implicitly telling them you do not trust them, and that you think they are not good enough to hold a lead or play in close games.
I dunno, personally when I played sports, that latter option sounds a hell of a lot worse than the former, especially if I was getting benched for a player I thought, or know, was worse than me. Its one thing to lose some minutes to Mcdavid in a close game, and another losing those minutes to Kunin or Goodrow etc.
It would also piss me off even more if it happens and we still consistently lose anyways. Why am I getting benched for a worse player, and watching us lose the game anyways. That would infuriate me and f*** my mental state up a hell of a lot more than making a bad pass or whatever in a tight game and losing because of it every now and again. At least I can learn from and do something about those mistakes, there is nothing I can do watching the Goodrow's of the world piss away leads every single game while I am on the bench.
I think there is also the question of whether you want the young players to learn sooner rather than later how to actually play in those close, meaningful moments of games. Is it better they learn now, while the team has no actual pressure to win, and losing the game sucks but ultimately does not mean a lot. Or would you rather they learn those hard lessons when we actually want to win games and losing games off of mistakes is far more meaningful and thus upsetting.
I dunno I find it hard to believe anyone would honestly say they'd be mentally stronger/happier by sitting and observing the team lose from the bench just so that they themselves are not the one who makes a mistake to lose the game.
