Mav is shit for Goose

Other than accidentally killing him, Mav kept acting like a fool with zero regard of his RIO priorities and wellbeing.
They continually get scolded for Mav's stunts, and Goose seems reluctant most of the time, saying stuff like that's a bad idea Mav, dont do it.

I understand Goose had the benefit of flying with one of the best, and possibly winning the trophy, but the risk involved with Mav always seems too much for such a nice and quiet family man.
Goose would have been better off with a more traditional pilot that shared his agenda of getting better at his job, instead of Mav's father complex and other dangerous insecurities.
