I think I will go the other way on this and say the kid Roslovic is getting an opportunity to reach for his potential. I hope he keeps fighting and taking advantage. I'm not going to make a lot of the benching of Laine. If he gives 100% effort from here out.. Torts will be fair.
I'm not sure if every defensive lapse on his part should be regarded as him not giving 100% effort though.
For the most part, Laine has been pretty responsible. He's usually the first guy back and often hangs back in order to allow the defenseman to rush forward. You don't see him "cheating for offense" like a lot of prominent wingers do.
His problem is more so that he's just not a great defense player, and probably never will be. He can read how to make offensive plays but he can't read defense the same way. A lot of what people deem to be a "lack of effort" is actually him just not being able to read the play correctly and positioning himself poorly. Even at best, he's just a body who blocks shots (which he does quite often, including the last game) and can prevent some passes going through, or force some giveaways, with his big stick and reach.
It's more of a matter of putting faith in him being able to cover up those mistakes with his offense, as well as putting him with compatible players. Anyone who thinks he's going to be turned into this great two-way player is kidding themselves, at best such efforts just succeed at nullifying his offense.
I would be more concerned about him not scoring goals than I would be about him turning the puck over or losing his man on defense. So far, at Columbus, he has done as advertised. It's just that what he brings to the table, doesn't seem to be what Tortorella is asking for. Obviously there has been some sort of a miscommunication between management and the coaching, and their respective vision for the Columbus franchise. Kekäläinen seems to want more offense while Tortorella is asking for more defense.
