Seven-time Formula 1 world champion Lewis Hamilton has compared the sport's so-called 'silly season' to the NFL, given the number of people moving between teams.
While there were plenty of driver moves ahead of the new season, sparked by Sebastian Vettel's retirement, Hamilton says a number of behind-the-scenes personnel also regularly move between teams.
Mercedes chief Toto Wolff recently claimed Red Bull had approached 100 of their employees and got 15 of them, while Aston Martin poached Dan Fallows from Red Bull to become their new technical director and Ferrari said they have hired 30 new engineers from other teams in recent years.
