Paddy Lowe pretty much admits having a (very poor) rookie like Stroll in the team cost them a lot of points and 4th place last season which begs the question why are they doing exactly the same thing this season with Sirotkin?!
William's are becoming a laughing stock by prioritising revenue from lackluster pay drivers over results on track and ultimately the reputation of the team. This will cost them prize money and sponsor revenue and is a strategy I would expect from a struggling backmarker not a midfield team with William's heritage.
