Haha, note how I said he did a lot to help Tavares, and neglected to mention the above.
That said, Tavares was deployed to mitigate his weakness and bolster his opportunities for success.
Domi was initially thrust into a situation well over his head (hard match L1), and then relegated to a misfit line while playing through a back injury. He's not the level of player that you'd want the coaching staff to have to orient the whole team structure around, but his deployment did him no favours, while he still gave what he had to the team.
