FILE - This Dec. 30, 2016, file photo shows Michigan safety Delano Hill, right, attempting to stop Florida State running back Dalvin Cook, left, during the first half of the Orange Bowl NCAA college football game in Miami Gardens, Fla. Home-run hitter with big-time acceleration, but ball security has been a problem and there are questions about his ability to run between the tackles. If he slips out of the first round, Cook will be a second-round steal. (AP Photo/Lynne Sladky, File)
