Giving up a puck when you're the last man back that directly leads to a clean breakaway ain't so hot. Kakko knew it was a major screw-up.
He got benched for a few shifts. Big effin deal.
If Torts was coaching, Kakko wouldn't have played another shift and would be benched in the next game.
In sports, the top players aren't held to the same standards. You might not like that, but it's a universal that you already know.
After a game like that, being negative about one player's minutes is staying on agenda out of stubborness. It's like the folks who have to bash Trouba every day, even if he plays a good game, and he did play a good game, even if it was his first of the season.
