The 6-foot-4, 200 pound junior out of Lovejoy (Ga.) missed his sophomore season with a torn muscle in his hip. It was a slow process that did not require surgery to get back, but he returned just in time for track season in the spring of 2013.
He is now 100-percent on the football field and he is one of the best in the country regardless of class.
Scout moved Williams up from the No. 7 receiver to No. 1 and from No. 71 overall into the top 20.
His head coach sees exactly what Scout sees.
"I tried to tell everyone that they just needed to see Preston play and they would be impressed. After going 85 yards on the first play last season, he came up limping, then missed the remainder of the season, but he is back, and he is special," said Lovejoy head coach Al Hughes.
"He has that it factor that you don't see a lot of. He has all the qualities you look for in size, vertical leap of 42 inches, hands, 4.4 speed in the 40 yard dash, and he has a great attitude to go with those things.
"There is not much, if anything he cannot do. He can change a game and he is a very exciting player."
Scout has spent time with Williams over the past month and he is about as humble as they come.
The success on the field, the commitment to Tennessee to play football, and all of the accolades he is getting will not change who he is.
"It is an honor to be a five-star prospect, but I am just going to keep being who I am. I am going to keep working hard, keep playing hard, and I am not going to change," Williams said.
"I am hungry, I want to be the best, and I know I can keep getting better. I want a state championship and that is what is on my mind right now. Being recognized as a five-star is an honor, but I want that state title."
Williams helped his team in a big way in round one with 275 yards receiving, four touchdowns, and an interception. You can see those highlights here.
He has that flare on the field, but he still wants to get better. He has the size you cannot coach, he rips the ball out of the air as a receiver, he runs past defenders, he is long and athletic, and he is a special talent.
Over 20 schools offered Williams, but he committed to Tennessee, his childhood favorite not long after his junior year began.
Lovejoy hosts Lowndes in round two of the Georgia State playoffs Friday night.
