#1 Stoffel Vandoorne
No real surprises here, it's Stoffel the Waffle who tops this dishonourable list. The Belgian promised much in Formula 1 after his brief cameo in 2016, but 2017 was difficult with an awful McLaren being produced at Woking.
While this year's entry was equally bad towards the end of the year, it started as a solid midfield runner, challenging the Haas' and Renaults in the first half of the campaign. While Fernando Alonso scored points in all of the first 5 races, Vandoorne scored on only 3 occasions, even finishing behind Alonso despite the Spaniard's car having significant aerodynamic damage.
From there, McLaren's and Vandoorne's form plummeted, the Belgian failing to score after the Spanish Grand Prix until Mexico, a thirteen race pointless streak. Like Bottas, Vandoorne possibly suffered due to his world championship winning teammate, but Stoffel still had a poor year and deservedly finds himself racing in Formula E instead of Formula 1.
He could work his way back into the sport one day, but 2018 was definitely his annus horriblus and he'll do well to recover from it.
