“Definitely not the all-time worst because there were zero expectations, but Connor Cook was heinous,” a Raiders fan said. The former Michigan State standout has one historic statistic accolade to his name. He was the first quarterback to make his first start in the postseason, but that was as good as it got for him.

He did throw a single touchdown in that game against the Texans. However, he also threw three interceptions and completed just 18 of 45 passes for 161 yards. That was effectively the end of his NFL career because he never played in the league again despite popping up in multiple preseasons and practice squads. Furthermore, he briefly signed up to play for the XFL, but the league fell apart.
