2013: Eli Manning, New York Giants
After being named to the Pro Bowl after the 2012 season, Eli Manning had an absolutely miserable season the following year, in a season in which the Giants finished with their first losing season in almost a decade. Not only did he finish with the third-worst completion percentage (57.5) of his career, but he was sacked a career-high 39 times as well. And when he was able to stand upright and throw passes, a lot of them went to the other team; he threw a career-high and NFL-high 27 interceptions that year. That season was one of the big reasons the Giants eventually brought in then-offensive coordinator (and current head coach… for now) Ben McAdoo.
