Scoring from the 3rd line has been a big issue, and with Kakko and Chytil out we are lacking depth (I think Kakko will be back this month hopefully). I think Othmann fits in nicely on the 3rd line with Cuylle and Bonino. Pitlick is hurt and is week to week, so I'd expect Brod will go down and play with Goodrow and Vesey on the 4th line. It is a good move to give Othmann a chance given the scoring depth need.
As for Bonino, he was brought here as a 4th liner to help the PK, add a defensive presence upfront, and win FO's, and he has done all of that well IMO. The issue is he has been forced into a 3rd line role, which is not the right spot for him, but is what is it right now. Once he can move back to the 4th line, he will be a solid player for us.
