Florida State has had a slew of talented running backs over the past 30 years, but Cook was the first to break the 1,000-yard barrier in his first season with the team. The next two seasons have only gotten better, ranking in the top 10 by breaking 1,600 yards (1,691 in 2015 ranked sixth in the FBS, 1,765 in 2016 ranked fifth), scoring 19 times as a rusher, and earning first-team All-ACC accolades each year. The speedy and shifty back was also named 2016 first-team All-American by the Associated Press and Walter Camp Foundation, among others. NFL teams will be interested in his medical checks, though, because of the hamstring issues he had throughout the 2015 season and the three shoulder surgeries he's had since high school.
