Tsunoda was outperforming DeVries every race by a longshot.
I just looked at the last three races and in two of them they finished next to each other and the third they were just two positions apart. That seems reasonable, unless you think Tsunoda also need to be replaced. I'm not trying to defend DeVries. I just think it's hard to tell if his low finishes are because of his lack of skills or just a slow car. Tsunoda has a lot more time in the car and he's not doing much.
