The forgotten man on the top 20 list, <PERSON> signed his $123 million deal with the Indianapolis Colts after a solid 2016 campaign where he started 15 games and threw 31 TDs. Luck was also sacked a league-high 41 times, however, and promptly underwent shoulder surgery on his throwing arm. The 28-year-old Stanford alumnus missed the entire 2017 season, but is poised for a return. Given just 38% of his salary is guaranteed, <PERSON> will be wise to avoid another sack-riddled season.
