Earlier this month, Arkansas running back Rawleigh Williams III made "one of the hardest decisions I've ever had to make," deciding to end his football career with two seasons of eligibility left.
A "stinger" that Williams suffered in the Razorbacks' final spring practice was an all-too-eerie reminder of the neck injury he suffered in the 2015 season, one that left him motionless on the turf for an extended period and briefly numb in a win over Auburn, providing an emotional scare that football players -- and their families -- never hope to experience, a reminder of how dangerous the sport can be.
