I have sympathy with De Vries. I get he's not hit the ground running but he wasn't woeful like some in recent years and 10 races isn't a lot to get settled. Getting beaten by Tsunoda isn't good, but the car seems poor. Helmut Marko's comments regarding Horner's 'warning' and yellow card were brutal so that combined with Red Bull's history and his slow start makes it's not surprising.
It would make more sense to me if it was to promote a young and promising Red Bull driver, rather than Ricciardo, given his results at McLaren. He'll probably make me eat my words now with a series of great drives!. With Vips gone and Lawson in a Super Formula title battle guess there wasn't really an option there.
Perez struggling won't have helped the situation, a closer season might have seen them have a constructors battle. I wonder if this is an eye on seeing if Ricciardo could get a seat there.
I agree, but it was probably the wrong team for him to choose in hindsight. I suspect had he gone to Williams he might have lasted the season at least.
