from walter football:
Dalvin Cook was dominant at Florida State. In fact, he was so great that many believed he would pass Leonard Fournette in the 2017 NFL Draft. It's extremely difficult to envision that happening now in the wake of the combine. Cook tested so extremely poorly that conspiracy theorists may begin to believe that he was replaced by an evil, less-athletic twin after being kidnapped. Cook's 40 wasn't horrible (4.49 at 210 pounds), but it wasn't good, and it certainly didn't make up for his awful vertical (30.5), broad jump (9-8) and 3-cone time (7.27). Sports analytics say that a running back as unathletic as Cook hasn't been drafted in the first round in nearly two decades.
Teams do have some off-the-field concerns about Cook and his character. He escaped some legal issues last year, but teams say that Cook has an entourage of gangbangers and they worry Cook drinks too much. Staying out of trouble is a concern that teams have. With Jameis Winston in the NFL, Cook carried the Florida State offense in 2015. He averaged 7.4 yards per carry on his way to 1,691 yards and 19 touchdowns. The sophomore also had 24 receptions for 244 yards and a score. As a true freshman in 2014, Cook averaged 5.9 yards per carry for 1,008 yards and eight touchdowns. He caught 22 passes for 203 yards, too.
