Haas were fucked in the last few season due to idiotic sponsorship deals. Magnussen's driving yesterday was impressive, I hope with few good results they find some serious sponsor to keep up the competitiveness.
As a fan of McLaren I'm really disappointed and afraid this season will be terrible seeing the engine supplier, Mercedes, struggling themselves.
Ferrari and Red Bull look strongest and will be a lot more interesting than watching Mercedes domination, although I expect them to recover around midseason.
