'There is still a fair amount of uncertainty on Williams, which is why he dropped five spots from last year's Top 20 rankings. The Bills have said they won't know for sure on Williams until he delivers his first hit during training camp and the preseason. Everyone involved is hopeful that he'll be able to take his starting spot and run with it, but it's not a guarantee until that event happens. If his neck reacts well to the physicality of the game, Williams will be the best safety on the roster and has the ability to be a difference maker from the safety position. If that all happens, expect his ranking to go up in 2017.'
